Two blocks are connected by a rope, as shown below. The masses of the blocks are 10kg for the lower block and 5kg for the upper
block . An upward applied force of magnitude F acts on the upper block. If F = 450N which of the following predictions about the acceleration of the two block system is correct?
1) The system accelerates downward with a magnitude 2g
2) The system accelerates downward with a magnitude 3g
3) The system accelerates upward with a magnitude 2g
4) The system accelerates upward with a magnitude 3g
1) The system accelerates downward with a magnitude 2g
2) The system accelerates downward with a magnitude 3g
3) The system accelerates upward with a magnitude 2g
4) The system accelerates upward with a magnitude 3g

The magnitude of the average impulsive force imparted to the ball if it is in contact with the bat is 6000 N
The mass of the baseball, m = 0.15 kg
The speed at which it moves, v = 30 m/s
Time at which the baseball was in contact with the bat, t = 0.75 ms
t = 0.75/1000 s
t = 0.00075 s
The impulsive force is given by the formula:
Substitute m = 0.15 kg, v = 30, and t = 0.00075s into the formula above:
The magnitude of the average impulsive force imparted to the ball if it is in contact with the bat is 6000 N
