In a local bar, a customer slides an empty beer mug down the counter for a refill. The height of the counter is 1.42 m. The mug slides off the counter and strikes the floor 2.20 m from the base of the counter. (a) With what velocity did the mug leave the counter? (b) What was the direction of the mug's velocity just before it hit the floor (below the horizontal)?

A projectile is launch from ground level at an angle of 30.6 degrees relative to the horizontal. It returns back to the ground after a time of 2.27 s. What was the initial speed of the projectile?

A person stands on a diving board and tosses a stone into a swimming pool. The stone is thrown from a height of 2.9 m above the water surface with a velocity of 2.8 m/s at an angle of 38° above the horizontal. As the stone strikes the water surface, it immediately slows down to exactly half the speed it had when it struck the water and maintains that speed while in the water. After the stone enters the water, it moves in a straight line in the direction of the velocity it had when. it struck the water. If the pool is 4 m deep, how much time elapses between when the stone is thrown and when it strikes the bottom of the pool? ttotal = S

A basketball player is running at 4.50 m/s directly toward the basket when he jumps into the air to dunk the ball. He maintains his horizontal velocity. (For each answer, enter a number.) (a) What vertical velocity (in m/s) does he need to rise 0.650 meters above the floor?m/s (b) How far (in m) from the basket (measured in the horizontal direction) must he start his jump to reach his maximum height at the same time as he reaches the basket?m

A horizontal projectile is shot with an initial velocity of 17.9 m/s from a height of 2.59 m above the ground. Neglecting air-resistance, what is the magnitude of the final velocity (m/s)
