Question 1 Correct 6.00 points out of 6.00 A 0.500 kg steel ball is dropped from a height of 4.00 m onto a horizontal steel slab. The collision appears elastic in that the ball rebounds to its original height. If the collision lasts for 2.00 × 10−3 s, which of the following is the impulse imparted to the ball and the average force applied to the ball during the collision? Select one: a. I = 8.49 kg•m / s F = 4.25 × 103 N b. I = 8.85 kg•m / s F = 4.43 × 103 N c. I = ...

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...
