A student drops a water balloon out of a dorm window 26 m above the ground. What is its speed when it hits the ground? _________ m/s

So this is the problem I am trying to figure out: A boy tosses a coin straight up to 2.2 m. Suppose the height when the coin leaves his hand is 1.3 m. What was the initial speed of the coin when it left his hand?

Evan is just leaving his house to visit his grandmother. Normally, the trip takes him 25 minutes on the freeway, going 55 mph. But tonight he’s running 5 minutes late. How fast will he need to drive on the freeway to make up the 5 minutes?

A very small steel bag with mass = 10.9g is dropped from a height of H=2.0m What is the minimum possible amount of time it takes for the ball to reach the ground? What is the maximum possible speed of the ball when it hits the ground?

1. A ball is thrown upward from the top of a 50 meter high building with an initial speed of 25 m/s.a. How much time does it take to reach the ground?b. What velocity does it have when it reaches the ground?

5. A small rock is thrown vertically upward with a speed of 12.0 from the edge of the roof of a 25.0 m tall building. The rock doesn't hit the building on its way back down and lands on the street below. Ignore air resistance. a. What is the speed of the rock just before it hits the street? b. How much time elapses from when the rock is thrown until it hits the street? c. Find the maximum height above the ground that the rock reaches. d. At what time after being released has the rock fallen 8.0 m below the roof edge? e. What is the ball's acceleration when it is 8.0 m below the roof edge? vy=25.18 m/s a. b. t = 3.79 s c. y 32.35 m d. t = 2.99 s e. ay = -9.8 m/s²

A rubber ball rebounds to 0.72 of the height from which it has dropped. It is first dropped from aheight of 6 meters onto level ground. a. After 2 bounces, what height does it rebound? Draw a sketch to help you. b. After how many bounces does it first rebound to a height less than 1 meter? (deals with sequences and series)

An object is thrown straight up with an initial velocity of 31 m/s. a. How high does it go in meters? b. How long is it in the air in seconds?

A small block has constant acceleration as it slides down a frictionless incline. The block is released from rest at the top of the incline, and its speed after it has traveled 6.60 m to the bottom of the incline is 3.80 m/s. Q: What is the speed of the block when it is 3.80 m from the top of the incline?

help solve two part question  A. A roller coaster begins at rest at the top of a 30 m hill. Find the velocity at a point 5 m above the bottom of the hill. B. A roller coaster begins at 6 m/s at the top of a 39 m hill. Find the velocity at a point 4 m above the bottom of the hill.
