Dana hits a volleyball so that it moves with an initial velocity of 6 m/s straight upward. If the volleyball starts from 2 m above the floor, how long will it be in the air before it strikes the floor?
Homework Answers
initial velocity = V0 = 6 m/sec
height = h= 2 m
time = t = ?
h = - V0 * t + 1/2 * g * t^2
2 = - 6 t + 0.5 * 9.8 * t^2
2 = -6 t + 4.9 t^2
by solving the equation
time = t = 1.497 sec = 1.5 sec

A ball is thrown vertically upwards with an initial velocity of 18.80 m/s, from the ground. How long is the ball in the air? (Neglect air resistance.) What is the greatest height reached by the ball? Calculate the time at which the ascending ball reaches a height of 12.8 m above the ground. A rocket, initially at rest on the ground, accelerates straight upward with a constant acceleration of 53.0 m/s^2, until the fuel is used up after 6.80s. What...

A rocket moves upward starting from rest with an acceleration of 20 m/s^2 for 5 s. It runs out of fuel at the end of this 5 s and continues to move upward, acted upon only by gravity. How high does it rise? Find the velocity of the rocket just before it hits the ground and how long it is in the air?

A 2.7-kg ball is thrown upward with an initial speed of 20.0 m/s from the edge of a 45.0 m high cliff. At the instant the ball is thrown, a woman starts running away from the base of the cliff with a constant speed of 6.00 m/s. The woman runs in a straight line on level ground, and air resistance acting on the ball can be ignored. 1.At what angle above the horizontal should the ball be thrown so that...

You throw your phone straight out horizontally so that is leaves your hand with a velocity of 15.6 m/s forward. When the phone leaves your hand, its vertical height is 1 m above the ground. Once it leaves your hand, it begins to fall while moving forward due to gravity pulling it downward. a. What is the phones initial velocity in the horizontal (forward) direction in the instant it leaves your hand? b. What is the phones initial velocity in...

For women's volleyball the top of the net is 2.24 m above the floor and the court measures 9.0 m by 9.0 m on each side of the net. Using a jump serve, a player strikes the ball at a point that is 3.03 m above the floor and a horizontal distance of 8.1 m from the net. (Enter your answers accurate to at least three significant figures.) (a) If the initial velocity of the ball is horizontal, what minimum...
