A 0.9 kg ball was thrown horizontally with a speed of 3.7 m/s. The ball hits the bottom of the rigid slender 2.3 kg bar which pivots about its top. Answer the following questions -3.7 m/s Figure 4 1.8 m (a) Explain what is happening from time zero to t, i.e., at the instant the ball hits the bar, and determine the speed of the ball and the angular speed of the bar. It should be a detailed but concise description of the simple mechanics event. (b) The effects of restitution on materials colliding are an important subject of study. Based on your knowledge, why the effects of restitution can be useful in engineering applications? Predict what would happen to the angular speed of the bar and the linear speed of the ball just after impact if the coefficient of restitution is 0.7. How would you interpret the outcome?

Squids rely on jet propulsion when a rapid escape is necessary, providedthey have filled their mantle with water prior to escape. An empty 1.5kg squid initially drifting at 1.6m/s pulls in 0.10kg of water in its mantle, then ejects this water at a remarkable 45m/s. How fast is this squid moving right after this ejection?

Suppose you are in a rocket with no windows, traveling in deep space far from other objects. Without looking outside the rocket or making any contact with the outside world, explain how you could determine whether the rocket is (a) moving forward at a constant 80% of the speed of light and (b) accelerating in the forward direction.
Dr. Liu is learning how to juggle. He tosses a tennis ball (probably bad choice since it is so bouncy) up at 2.0 m/s at a height 1.6 m above the floor and attempts to use the other hand to catch the falling ball. The ball hit the floor at his feet. How long was Dr. Liu's tennis ball in the air (between tossing and landing)? Ignore air drag. He should probably practice tossing his juggling ball at the same height and same speed before attempting to juggle. Hint: You can set the final position to be zero.
A farm truck moves due east with a constant velocity of 9.50 m/s on a limitless, horizontal stretch of road. A boy riding on the back of the truck throws a can of soda upward (Fig. P3.54) and catches the projectile at the same location on the truck bed, but 16.0 m farther down the road. (a) In the frame of reference of the truck, at what angle to the vertical does the boy throw the can? (b) What is the initial speed of the can relative to the truck? (c) What is the shape of the can’s trajectory as seen by the boy? An observer on the ground watches the boy throw the can and catch it. In this observer’s frame of reference, (d) describe the shape of the can’s path and (e) determine the initial velocity of the can.
