An object is moving with uniform accleration. Its velocity after 5 sec is 25m/s and after 8 sec,it is 34 m/s. Find the distance travelled by this object in 12th second. Ans. 44.5 A particle starts with a velocity of 100 cm/s and moves with –2 cm/s2 acceleration. When its velocity be zero and how far will it have gone? Ans. 50s , 25m m/s. After 7 a time interval ∆t, the velocity of the body is reduced by half, and after the same time interval, the velocity is again reduced by half. Determine the velocity (in ms–1 ) vf of the body after a time interval 3∆t from the moment when the constant force starts acting. Ans. 10 A certain constant force starts acting on a body moving at a constant velocity A particle is moving with uniform acceleration, in eighth and thirteenth second after starting it moves through 255 cm and 225 cm respectively. Find its initial velocity and its acceleration. Ans. 300 cm/s, 6 cm/s2 The speed of the train is reduced from 36 km an hour to 9 km per hour whilst it travels a distance of 150 metres, if the retardation be uniform, find how much further it will travel before coming to rest. Ans. 10 m A train takes 5 minutes to cover a distance of 3 km between two stations P and Q. Starting from rest at P, it accelerates at a constant rate to a speed of 40 km/h and maintains this speed until it is brought uniformly to rest at Q. If the train takes three times as long to decelerate as it does to Ans. 15s accelerate, find the time taken by the train to accelerate. A train stops at two stations P and Q which are 2 km apart. It accelerates uniformly from P at 1 m/s2 for 15 seconds and maintains a constant speed for a time before decelerating uniformly to rest at Q. If the deceleration is 0.5 m/s2, find the time for which the train is travelling at a constant speed. Ans. 111 s A car is moving along a straight line. It is taken from rest to a velocity of 20 m/s by a constant acceleration of 5 m/s2. It maintains a constant velocity of...

Mathematics and its importance
Mathematics is a fundamental part of human thought and logic, and integral to attempts at understanding the world and ourselves. Mathematics provides an effective way of building mental discipline and encourages logical reasoning and mental rigor. In addition, mathematical knowledge plays a crucial role in understanding the contents of other school...

...experiment, the focus is all about Friction. Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction like fluid friction which describes the friction between layers of a viscous fluid that are moving relative to each other; dry friction which resists relative lateral motion of two solid surfaces in contact and is subdivided into static friction between...

...the groups tried to prove their supremacy through mass killings. The police remained a mute witness to these killings, as they lacked the means to take any action.
The Ranvir Sena has now significantly weakened with the arrest of its top brass. The other groups are still active.
There have been arrests in various parts of the country, particularly those made by the Delhi and Mumbai police in the recent past, indicating that extremist/terrorist outfits have been spreading their...

...Does Maths Help You with OtherSubjects?
Maths helps you with othersubjects because it enables the student to be a logical thinker and have skills in statistical analysis. Maths also gives skills which are closer to those used in the workplace as opposed to skills learned in othersubjects. Realistically speaking, numbers, problem solving and equations are actually...

...Math and Science
The math teacher can teach students about exponential notation. Once students become proficient in reading and writing numbers in exponential form, and in converting numbers between exponential, factor, and standard form, they can apply this knowledge to topics in science. For example, they can write the distance between the sun and each planet using scientific notation. For advanced students, you can teach them about negative exponents. Then...

...involves concept of a valid contract, pre-contractual statements, express term and misrepresentation.
A valid contract is established between Beauty and Stylish when an offer is accepted and there is intention for both parties to create legal relations. An offer refers to the expression of willingness of the offerer to be contractually bound by an agreement if his or her offer is properly accepted. It has to be clear and certain in terms. It must also be communicated to the...

...Example 3:
The art club has 4 members. They want to choose a group of three to compete in a regional competition. How many ways can three members be chosen?
Because the members of the group do not have specific jobs, order does not matter. In other words, choosing Taylor, Aubrey, and Justin in the same as choosing Aubrey, Taylor, and Justin. Therefore, we need to use the combination formula to solve this problem.
