Question 1: The spring is placed between the wall and the 40 lb block. If the block is subjected to a 250 lbs force as shown, determine its velocity when S = 6 inches. When S = 0, the block is at rest and the spring is uncompressed. The coefficient of friction between the block and the ground is µ_k = .1

Question 2: When a ball is released from rest at a height of 5 ft above the floor, it bounces to a height of 3.5 feet. If that same ball is thrown at the floor with a velocity of 30 ft/s and is released at 3.5 feet above the floor, how high will it bounce? The ball weighs 1.25 lbs.
