A tennis ball of mass 57 g travels with velocity < 74, 0, 0 > m/s toward a wall. After bouncing off the wall,?
A tennis ball of mass 57 g travels with velocity < 74, 0, 0 > m/s toward a wall. After bouncing off the wall, the tennis ball is observed to be traveling with velocity < -68, 0, 0 > m/s.
1. What is the change in the momentum of the tennis ball?
2. What is the magnitude of the change of momentum of the tennis ball?
3.What is the change in the magnitude of the tennis ball’s momentum?
Good 'ole Webassign. My question was a bit different but i'll try my best.
1) always think, final - initial. so we have a final velocity of -68 and initial of 74.
so take -68*.057 to get final magnitude, and then subtract final magnitude of (74*.057kg)
=answer should be around -8 or -9
y and z will be zero because they are 0 in the final and initial velocities
2) the magnitude of the change in momentum of the ball will be the absolute value of the x value in question 1.
3) now take the magnitude of the final, AKA 68, and multiply by .057, then subtract (74*.057)
=answer. should be a small negative one.
