Impulse and momentum - Study guides, Class notes & Summaries

Linear Momentum and Collisions ANSWERS TO QUESTIONS *Q9.1 (a) No. Impulse, F∆t, depends on the force and the time for which it is applied. (b) No. Work depends on the force and on the distance over which it acts. *Q9.2 The momentum magnitude is proportional to the speed and the kinetic energy is proportional to the speed squared. (i) (ii) The speed of the constant-mass object becomes 4 times larger and the kinetic energy 16 times larger. Answer (a). The speed an...

Kinetic Energy and Jump Height Correct Answer-The relationship between flight height yflight and takeoff velocity vtake-off can be obtained by applying the law of conservation of mechanical energy to the flight phase of the jump. The mechanical energy (E) of the jumper is the sum of the kinetic energy (KE = ½mv2) and gravitational potential energy (PE = mgy). In vertical jumping the effect of air resistance is negligible, and so in the flight phase the jumper can be considered as a projectile i...
