1. Two ships P and Q are moving along straight lines with constant velocities. Initially P is at a point O and the position vector of Q relative to O is (6i + 12j) km‚ where i and j are unit vectors directed due east and due north respectively. The ship P is moving with velocity 10j km h–1 and Q is moving with velocity (−8i + 6j) km h−1. At time t hours the position vectors of P and Q relative to O are p km and q km respectively. (a) (b) (c) Find p and q in terms of t. (3) Calculate the distance

Length of the Pendulum Trigonometry was used in order to calculate the unknown length of the arm of the claw. tanθ = o/a tanθ = x/18 x = 18tan42° = 16.21m Length of the pendulum = 16.21 + 1.54 = 17.7m Observation Point Approximately 18 meters. Triangular device used to measure the angle of elevation to the centre axis of the claw - 42° angle. It was estimated that the pendulum would be off the floor at the height of a person’s hip. One of the class member height was

Sketch a velocity versus time and displacement versus time for a car approaching a red traffic light and then leaves it as the light turn green. 2. Jimmy took 8 hrs to drive his Civic from KL to Kota Bharu which was about 400 km away. What was the average speed of Jimmy in km/h? Why‚ in this case was the term average speed used over velocity? 3. A ball rolls with a velocity of 20 m/s on the ground and comes to a stop

Isokinetic dynamometry testing on male university sport and exercise science students looking at Hamstring/Quadriceps ratio‚ peak torque‚ peak torque to body mass ratio and power. Abstract Isokinteic dynamometry testing is important in monitoring injury and performance. There are few studies that have looked at male university sport and exercise science students bilateral difference of the hamstrings and quadriceps at 60˚s and 180˚s.The purpose of the study was to look at injury and performance

Experiment 2: Kinematics of Human Motion Laboratory Report Leopoldo Luis A. Gueta‚ Lady Lian Lagamayo‚ Val Ian Caleb Leus‚ Kimberly Anne C. Macarilay Department of Math and Physics College of Science‚ University of Santo Tomas España Street‚ Manila Philippines Abstract Kinematics is the branch of classical mechanics that describes the motion of bodies and systems without consideration of the forces that cause the motion. There are four activities done in this experiment. Graphical analysis

What is Kinematics? Kinematics is the geometry of pure motion - motion considered abstractly‚ without reference to force or mass. Engineers use kinematics in machine design. Although hidden in much of modern technology‚ kinematic mechanisms are important components of many technologies such as robots‚ automobiles‚ aircraft‚ satellites‚ and consumer electronics‚ as well as biomechanical prostheses. In physics‚ kinematics is part of the teaching of basic ideas of dynamics; in mathematics‚

requirement of CPR action‚ a three-prismatic-universal-universal (3-PUU) translational parallel manipulator (TPM) is designed and developed for such applications‚ and a detailed analysis has been performed for the 3-PUU TPM involving the issues of kinematics‚ dynamics‚ and control. In view of the physical constraints imposed by mechanical joints‚ both the robot-reachable workspace and the maximum inscribed cylinder-usable workspace are determined. Moreover‚ the singularity analysis is carried out
