A baseball player swings his bat with an angular velocity of 20 rad/s when he hits a baseball traveling perpendicular to the surface of the bat at 120 ft/s. The bat weighs 2 lb and the baseball is 0.32 lb. The coefficient of restitution between the ball and the bat is 0.7. The bat is 3.5 ft long and the end of the bat is 5.5 ft from the point of rotation. Assuming the bat is a slender rod of uniform mass, determine the velocity of the ball as it comes off the bat. Also determine the distance the ball will travel if it comes off the bat at an angle of 50°.

A 2kg mass is initially traveling at a velocity of 0.95 m/sec. Kinetic friction coefficient between the surface and the mass is 0.5. How far does the mass travel before stopping? Provide your answer in millimeters, but do not include units in your submittal.
A lightweight drone (1.00 kg) is launched at 800 m high and moves upward at a constant velocity (whileignoring the effects of gravity only on the drone). The balloon, when measured at a horizontal distance fromyou, is about 1600 m away from you. At the moment when the drone moves, you shoot a bullet (weight =180g) with an initial velocity of 1009 m/s at a fixed angle α, where sin α=3/5 and cos α= 4/5. (g = 9.8 m/s2) d. Provided that the collision is inelastic, calculate the speed after the collision.e. Calculate the height the two objects taken from the impact up to the maximum height before it startsfalling to the ground.
A car with a mass of 1100 kg is traveling at 50 km/hr when it locks up its brakes, stopping over a distance of 18 meters. If the same car were to lock up its brakes when traveling 80 km/hr how far would you expect the car to slide before coming to a stop? (Hint: assume the same friction force in both cases) (Solution: d = 46.06 m)
