A student standing on the ground throws a ball straight up. The ball leaves the student's hand with a speed of 14.0 m/swhen the hand is 2.50 m above the ground. How long is the ball in the air before it hits the ground? (The student moves her hand out of the way.) Express your answer with the appropriate units.

9, Galileo throws a rock from the top of the Leaning Tower of Pisa at an upward angle of 69.00 with speed vo. The rock is in flight for 5.2 s and hits the ground 15 m from the base of the building. Ignore air resistance and ignore the fact that the two tilts a bit. a) What is the speed vo? Vo b) How high off the ground is the top of the tower? Height of tower c) What...

A ball is thrown up from the top of the tower. For parts a-c, state whether the ball's acceleration is larger than g, equal to g, zero, or -g (assume up is positive and that g = 9.80 m/s). 3. a. Just after leaving your hand and you are no longer touching it. b. When the ball is at the top of its path. c. Just before hitting the ground. d. Draw graphs of position vs. time, velocity vs. time,...

A student standing on the ground throws a ball straight up. The ball leaves the student's hand with a speed of 14.0 m/s when the hand is 1.90 m above the ground. How long is the ball in the air before it hits the ground? (The student moves her hand out of the way.) Express your answer with the appropriate units.

1. A person standing at the origin of the coordinate system throws a ball into the air at an angle 0 with the horizontal with a speed vo. (a) State the law of conservation of mechanical energy. (2 marks) (b) Write down vector equations for the acceleration, the velocity and the position of the ball. What is the shape of the trajectory that this ball describes?

A man is standing on a ledge when he throws a ball. The speed of the ball when released from his hand is 20.0 m/s . The ball is 45.0 m above the ground when released from the man's hand. On the ground below, a boy begins running away from a point directly below the man on the ledge at a constant speed of 6.00 m/s. The boy runs in a straight line along the ground. As the boy runs,...

A student at the top of a building throws a red ball upward with speed v0 and then throws a blue ball downward with the same initial speed v0. Immediately before the two balls reach the ground, which of the following statements are true? (Select all that apply.) A. The acceleration of the blue ball is greater than that of the red ball. B. The speed of each ball is greater than v0. C. The speed of the red ball...

Tallula is standing on the roof of her apartment building. She is opening a gift she just received in the mail. The gift is from Bob. She opens the attractively-wrapped packed to find a zucchini inside. Tallula hates zucchini. She throws the zucchini straight down with a speed of 11.32 m/s. The zucchini hits the ground 3.17 s later. If the zucchini has a mass of 0.266 kg, what was the height of the zucchini above the ground in metres...
