You throw a tennis ball straight upward. The initial speed is about 12 m/s. A)How long will it take for the ball to reach its maximum height? B)What is the maximum height that the ball will reach? The initial position of the ball is at the height y0 = 0 m.

While standing at the edge of the roof of a building, a man throws a stone upward with an initial speed of 5.89 m/s. The stone subsequently falls to the ground, which is 13.1 m below the point where the stone leaves his hand. At what speed does the stone impact the ground? Ignore air resistance and use g = 9.81 m/s2 for the acceleration due to gravity. impact speed: How much time is the stone in the air? elapsed time: m/s

Hello. I am working on a problem with motion. The questions asks me to calculate the maximum height (h1),  total time (t2), and speed of a ball right before it hits the ground. The question states that A person is throwing a ball upward into the air with an initial speed Vo = 10m/s. Assume that the instant when the ball is released, the person's hand is at a height ho = 1.5m. The speed of the ball at its peak height is zero, and the question needs to be solved in ascending part and descending part. I don't understand how to solve for the maximum height. What is the correct formula to use and why? For other questions like this, I will be able to solve them if I know the formulas for the ascending of the ball and the descent of the ball as well as the explanation. Thank you. For the sake of the question, the ball is being thrown straight up.

A punter kicks a ball at an angle of 75 degrees with an initial velocity of 15 m/s. What is the maximum height of the ball? (Assume his foot hits the ball 1 meter above the ground). Include a drawing and all steps. Use the projectile motion equations.

Hank Huckleberry, who is the quarterback for the Kennesaw Kilowatts in the Metro Metric Football League, where all distances in the field are measured in meters. Hank throws the ball with an initial velocity of 16 m/s at an angle which is 48 degrees up from north. He releases the ball from a height of 1.8 m above the field.  How long does it take from the time of the throw until it lands?

A baseball is thrown with an initial speed of 37.5 m/s at a 42.0° angle in the absence of air resistance. a) What is the maximum height reached by the baseball? b) What is the magnitude and direction of the baseball's velocity at t = 2.50 s? c) What is the ball's height when it has traveled a horizontal distance of 55.0 m?

A rocket is fired at a speed of 83.0 m/s from ground level, at an angle of 45.0° above the horizontal. The rocket is fired toward an 12.5-m high wall, which is located 21.0 m away. The rocket attains its launch speed in a negligibly short period of time, after which its engines shut down and the rocket coasts. By how much does the rocket clear the top of the wall? Number i Units

Freya clears a crossbar while pole vaulting. She releases the pole before she achieves her peak height.  It takes her 2 seconds to fall from her peak height to the landing pit.  The landing pit is 1.5 m high.  How high above the ground was Freya at the peak height of her vault?

Mt. Asama, Japan, is an active volcano complex. In 2009, an eruption threw solid volcanic rocks that landed far from the crater. Suppose that one such rock was launched at an angle of θ = 57.6 degrees above horizontal, and landed a horizontal distance d = 880 m from the crater, and a vertical distance h = 940 m below the crater. a) what is the initial speed of the rock in m/s? b) how long in secs was the rock in the air?

A ball is thrown upward from roof top, 90 m above the ground. The ball rises, then falls and hits the ground. Ignore air resistance. a) What is the initial velocity of the ball, if it takes the ball 9.4 s to hit the ground? b) What is the maximum height reached by the ball?
