Please provide solutions for the correct answers. Thank you!

Miley came in with a wrecking ball A with a mass of 500 kg. It is released from rest from height h and it rammed on block B which has a mass of 1200kg. Block B is originally resting on the floor but after the
collision, it gains a speed of 4.20 m/s and travels a distance d on the level surface. The coeficient of restitution between the wrecking ball A and block B is 0.69. The coefficients of friction between block B and
the horizontal surface are us - 0.40 and k -0.25, respectively.
A: 500 kg
B: 1200 kg
1. Which of the following best approximates the acceleration of block B as it glides along the floor?
245 ms2 o the leh.
2. Which of the following is closest to the distance d the block travels before coming to a complete stop?
3.60m v
3. Which of the following forces produces an impulse on block B that is NOT negligible?
The force eserted by wrecking ball A on block
4. Which of the following is the nearest value to the velocity of the wrecking ball A immediately after its impact with block e7
1.630 m/s to the left v
5. Which of the following best represents the height h of the wrecking ball when it is released?
0.1355 m X
