the board. If it enters with a speed of 450 m/s and emerges with a speed of 220 m/s‚ what is the bullet’s acceleration as it passes through the board? Answer: –550 km/s2 5. A particle confined to motion along the x axis moves with constant acceleration from x = 2.0 m to x = 8.0 m during a 2.5s time interval. The velocity of the particle at x = 8.0 m is 2.8 m/s. What is the acceleration during this time interval? Answer: 0.32 m/s2 6. A package is dropped from a helicopter moving upward

vertical motions which are independent from each other‚ known as vector components. For an object to be considered a projectile‚ it must not be self-propelled. Projectiles move horizontally at a constant velocity. However‚ they undergo uniform acceleration in the vertical direction‚ which is caused by gravity. An important aspect of projectile motion is that the time it takes for the object to travel on the Y axis is exactly the same as the time it takes to travel on the X axis. A practical example

1 Centripetal Acceleration Imagine a marble sitting on a rotating turntable. The different vectors representing velocity for the travelling marble are shown below. Notice that the size of the vector remains the same but the direction is constantly changing. Because the direction is changing‚ there is a ∆v and ∆v = vf - vi ‚ and since velocity is changing‚ circular motion must also be accelerated motion. vi ∆v vf -vi vf2 If the ∆t in-between initial velocity and final velocity

a factor in the practical has a big impact on the outcomes that you get‚ as there is nothing acting against gravity hence a greater acceleration the object has. Having Air Resistance However having air resistance also changes the outcome of the practical because the air resistance is acting against the force of gravity hence the object has less acceleration and once the air resistance is stronger then the terminal velocity that is when the object is going at a small velocity.

Introduction The purpose of this section is to introduce the concepts of displacement‚ velocity‚ and acceleration. For the sake of simplicity‚ we shall restrict our attention to 1-dimensional motion. Displacement Consider a body moving in 1 dimension: e.g.‚ a train traveling down a straight railroad track‚ or a truck driving down an interstate in Kansas. Suppose that we have a team of observers who continually report the location of this body to us as time progresses. To be more exact‚ our observers
