Cylinder A. has a mass of 3 kg and cylinder B has a mass of 8 kg.
Determine the speed of AA after it has moved 2 mm starting from rest. Neglect the mass of the cord and pulleys.
Q17. As shown in the image below, the 0.5-kg ball strikes the rough ground and
rebounds. The directions of its velocities before and after the strike are shown. If the
speeds are vi = 21 m/s and v2 = 13 m/s, determine the magnitude of the impulse (in
N-s) the ground exerts on the ball. Assume that the ball does not slip when it strikes
the ground, and neglect the size of the ball and the impulse produced by the weight
of the ball. Please pay attention: the numbers may change since they are
randomized. Your answer must include 2 places after the decimal point.

Answer
The figure shows a cart A of mass ma = 35 kg carrying a block B of mass mg =
25 kg by a cord having a length of 2 m. If the system is released from rest when block B
is displaced by 30° as shown, calculate the velocities of A and B when B passes directly
under A (i.e. 0 = 0.0°). Neglect friction.
