A stone is thrown vertically upward from the ground with a speed of 30 meters per second. Calculate the time of flight of the stone in coming back to its origin.

A person sitting on the ground floor of a building notices through the window, of height 1.5 m, a ball dropped from the roof of the building and crosses the window in 0.1 s. What is the velocity of the ball when it is at the topmost point of the window? (g-10 m/s²) (1) 20 m/s (2) 15.5 m/s (3) 14.5 m/s (4) 4-5 m/s

1. An object is thrown vertically upward from the ground and is seen to pass the top of a building with a speed of 15 m/s. If height of the building is 30 m: (a) With what velocity was the object thrown from the ground? (b) What is the maximum height reached by this object? (c) When will the object reach the ground again?

A man in the back row of 1510 of a theatre wishes to hit a statue in front of the theatre screen with a ball. The statue stands 2 meters tall and the baller is sitting in an elevated seat, 10 meters above the floor the statue stands on. The horizontal distance from the spit baller to the statue is 10 meters. The time of flight of the spit ball is 0.6 seconds given an initial ball speed of 15m/s. Find the velocity of the ball when it is fired.

An object fell from the balcony of a high-rise building. It hit the ground with a final speed of 14 m/s. The vertical height of the balcony must have been?

You're helping a friend move in to their apartment on the second floor, and decide it makes more sense to throw a box straight up from the ground to the open window in the apartment, 5.00 m above the ground. Your friend leans out the window and catches the box while it's moving upward at 2.40 m/s. What is the speed of the box as it left your hand?

I was standing on the side of a 10-m foot bridge, holding a ball while watching a car approaching the bridge at uniform speed. When the car was 15 meters away from where I was standing, the ball that I was holding slipped in my hand and the car arrived at the bridge when the ball hit the ground. What was the speed of the train? ( Assume that the final velocity of the ball is NOT zero)

At a moment when a rocket is 1120 m above the ground, it is traveling straight upward with a speed of 955 m/s. At this instant a small piece detaches from the rocket and begins freefall travel. 1. a) Find the velocity of the piece the instant before it hits the ground. b) Find the time required for it to reach the ground.

h=-16(2)^(2)-30(2)+220, where h_(0) is the height of the object when t=0 and v_(0) is the velocity of the object at time t=0 (c) How far does the rock fall in 2 seconds if you throw it downward with an initial velocity of 30 feet per second?

A student who aspires to ace his quiz in Phys134 went to a wishing welI. He dropped his first 10-peso coin and made a quick wish. Two seconds after he dropped his first coin, he threw another 10-peso coin vertically downward with a speed of 30m/s. How long will it take the second coin to overtake the first? * 3.8 s 1.9 s 2.9 s The second coin will never overtake the first coin
