For both questions, consider the following: A 5 kg and 8 kg block are on a horizontal table. The 5 kg block is initially at rest and the 8 kg block is initially moving directly toward the 5 kg block with velocity 4 m/s. The two blocks stick together and slide off the table. You want to determine the speed of the blocks immediately before they hit the ground. You may assume that the blocks lose no energy due to friction with the table or by air resistance. 0.60 m 17.

Question
For both
questions, consider the following: A 5 kg and 8 kg block are on a
horizontal table. The 5 kg block is initially at rest and the 8 kg
block is initially moving directly toward the 5 kg block with
velocity 4 m/s. The two blocks stick together and slide off the
table. You want to determine the speed of the blocks
immediately before they hit the ground. You may assume that the blocks lose no energy due to friction
with the table or by air resistance.
