A 475 gram ball is traveling horizontally at 12.0 m/s to the left when it is suddenly struck horizontally by a bat, causing it to reverse direction and initially travel at 8.50 m/s to the right
If the bat produced an average force of 1275 N on the ball, for how long (in ms) was it in contact with the ball?
The acceleration of a ball as it rolls down a ramp is 4 m/s2 . The ball is referred to 2 s after it starts to roll. The acceleration in m/s2 after starting from rest is
a. 0 d. 8 b. 2 e. 16 c. 4
