At the same instant, a student is running on the ground at a distance of 30 m from the building. Determine: (a) the time it takes the ball to reach the maximum height. | (b) the maximum height the ball reached (with respect to the ground). (c) the time it takes the student to catch the ball at the bottom of the building. (d) the average velocity of the student if he is to catch the ball on the ground.

A hot-air balloonist, rising vertically with a constant velocity of magnitude 5.00 m/s, releases a sandbag at an instant when the balloon is 40.0 m above the ground. After it is released, the sandbag is in free fall. Compute the position and velocity of the sandbag at 0.250 s and 1.00 s after its release. How many seconds after its release will the bag strike the ground? With what magnitude of velocity does it strike the ground? What is the greatest height above the ground that the sandbag reaches?
An inquisitive physics student and mountain climber climbs a 51.0-m-high cliff that overhangs a calm pool of water. He throws two stones vertically downward, 1.00 s apart, and observes that they cause a single splash. The first stone has an initial speed of 2.06 m/s. (b) What initial velocity must the second stone have if the two stones are to hit the water simultaneously?
A toy rocket is launched vertically from ground level (y=0m), at time t=0.0s. The rocket engine privides constant upward acceleration during the burn phase. At the instant the engine burnout, the rocket has risen to 64m and acquired a velocity of 60 m/s. The rocket continues to rise in thr unpowered flight, reaches maximum height, and falls back to the ground. What is the time interval during which the rocket engine provides upward acceleration?

A boat is cruising in a straight line at a constant speed of 2.5 m/sm/s when it is shifted into neutral. After coasting 11 mm the engine is engaged again, and the boat resumes cruising at the reduced constant speed of 1.5 m/s. Assuming constant acceleration while coasting, how much time did it take for the boat to coast the 11 mm?
