A hot air balloonist rising vertically with a constant velocity of magnitude 5 m/s, releases a sandbag at an instant when the balloon is 40 m above the ground. After it is released, the sandbag is in free fall. How many seconds after its release will the bag strike the ground? With what speed does it strike the ground? a) 3.41 s, 28.4 m/s b) 2.86 s, 28 m/s c) 2.86 s, 33 m/s

You throw a ball straight up from a roof of a building. The ball leaves your hand at a point even with the roof railing with an upward speed of 15m/s. The ball is then in free fall. On its way back down, it just misses the railing. After 6.0s from release, the ball then hits the ground. What is the velocity of the ball upon impact on the ground? 198.5m/s -198.5m/s 352m/s -352m/s
While standing at the edge of the roof of a building, a man throws a stone upward with an initial speed of 7.39 m/s. The stone subsequently falls to the ground, which is 19.1 m below the point where the stone leaves his hand. At what speed does the stone impact the ground? Ignore air resistance and use ?=9.81 m/s2 for the acceleration due to gravity. impact speed: How much time is the stone in the air? elapsed time:
A ball is thrown vertically upward from the top of a building with an initial velocity of 20 m/s at an initial height of 50 m above the ground. The ball just misses the roof on its way down. a) Determine the time needed for the ball to reach the ground.b) Determine the velocity and position of the ball at t=5 sec
A breaststroke competition consists of swimming back to the opposite end and back to where you started. Suppose a swimmer completes the first 50 m of the 100 m breaststroke in 39.1 seconds. When he reaches the opposite end of the 50 m long pool, he turns back and swims to the starting point in 42.5 seconds. What is the swimmer's average speed for the return leg only?a) 1.18 m / sb) 1.23 m / sc) 0.12 m / sd) 0 m / s

Both stones hit the water below the bridge at the same time. a)For how much time is the first stone in free fall? b)What is the distance from your hand to the water? c) What is the velocity (magnitude and direction) of the first stone when it hits the water?
An elevator starts from rest and moves upward, accelerating at a rate of 1.2 m/s2 until it reaches a speed of 7.8 m/s, which it then maintains. Two seconds after the elevator begins to move, a man standing 12 m above the initial position of the top of the elevator throws a ball upward with an initial velocity of 20 m/s. Determine when the ball will hit the elevator.
