Jack drops a stone from rest off of the top of a bridge that is 24.8 m above the ground. After the stone falls 6.6 m, Jill throws a second stone straight down. Both rocks hit the water at the exact same time. What was the initial velocity of Jills rock? Assume upward is the positive direction and downward is the negative. (indicate the direction with the sign of your answer.)

John kicks the ball and launches it into the air with an angle of 32° to horizontal. If it's initial velocity is 12 m/s, what is the maximum height the ball reached?

A ball is thrown upward from the ground with initial velocity vi = 19 m/s and reaches height of h above the ground before falling back down. Take the upward direction to be positive. Refer to the figure. Neglect air resistance. 1) Enter an expression for the height of the ball at a given time, h, the ball reaches in terms of the velocity at the current height vh, the initial velocity vi, and the acceleration a.  2) Enter an expression for the time it takes for the ball to travel from the ground to the a given height, Δt, in terms of the initial velocity vi, the velocity at that height vh, and the acceleration a.

A deer is running along the horizontal direction with a constant velocity of 14 m/s. The moment the deer passes a tiger, the tiger starts chasing the deer with an initial velocity of 4.5 m/s. Finally, the tiger catches the deer in 15 s. What is the acceleration of the tiger in m/s? Note write your answer with one decimal place Answer.

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?

A stone is thrown at 16 m/s with an angle of 40° above the horizontal from the rooftop of the building 56 m above the ground.  How long will it take for the stone to reach the ground?  What is the velocity of the stone just before it strikes the ground?

A young child uses a slingshot to launch a rock straight up at a speed of 12 m/s and then catches it at the point from where he launched it. What is the maximum height that the rock reaches?

A student fires a cannonball vertically upwards with a speed of 31.0m/s. Determine all unknowns and answer the following questions. Neglect drag and the initial height and horizontal motion of the cannonball. What was the cannonball's maximum height? unit How long did the cannonball rise? unit What was the cannonball's total flight time? unit

Please do not reject this question I really need help with it. A) A distress rocket is launched from the top of a hill on the edge of the ocean. Its height above sea level, in meters, at time t, expressed in seconds, is represented by the function h(t) = -4.9t^2 + 16t + 200. I)What is the initial velocity of the distress rocket? II) What is its height at launch? III) How fast does the distress flare goes down, 6 seconds after being launched? B)With the function (shown in the image down below) II) Determine the slope of the tangent at the point whose abscissa is x = 2. II) Determines the equation of the tangent at the point whose abscissa is x = -3.

A worker drops a can of paint from the top of his ladder 3.5 m tall .What is the velocity of the can of paint as it strikes the ground? Luckily the can of paint was not open. In order for it not to open and splatter on the ground the painter co-worker must have reacted quickly to catch the can of paint. How much time did the painter's co-workers have in order to catch the can of paint before it fell to the ground?
