You throw a stone straight down into a water well.  The stone starts from a height of 1 meter above the ground and strikes the water 10 meters below the ground.  You throw it with a speed of 15 m/s downward.  The stone strikes the water 0.611 seconds after it is thrown.  What is the acceleration of the stone?  Assume

OK, yet another strange awakening in a room with no windows. This time you drop a ball from a height of 1.79 m and it hits the floor 0.423 s after you drop it. This time you suspect you are on a rocket that has just left the surface of the Earth, and is still not too far above the ground. What do you deduce the rocket s acceleration to be?

A piano has been pushed to the top of the ramp at the back of a moving van. The workers think it is safe, but as they walk away, it begins to roll down the ramp. If the back of the truckis 1.0 m above the ground and the ramp is inclined at 20°, how much time do the workers have to get to the piano before it reaches the bottom of the ramp?

A bicycle has a constant velocity of 10 m/s. A person starts from rest and begins to run to catch up to the bicycle in 30 s when the bicycle is at the same position as the person. What is the acceleration of the person?

A crow flies carrying a shiny rock. The crow reaches an altitude of 65m and is flying 34.5 m/h. It releases the rock. Find the time it will take the rock to hit the ground below, the horizontal distance the rock will travel before it hits, and the speed of the rock when it hits the ground

An Olympic diver is on a diving platform 9:40 m above the water. To start her dive, she runs off of the platform with a speed of 1.18 m/s in the horizontal direction. What is the diver's speed, in m/s, just before she enters the water? m/s Additional Materials

A ball is thrown into a wall at a speed of 20 m/s and bounces off going 10 m/s in the opposite direction 0.2s after hitting the wall. What is the acceleration of the ball?

A plane releases a package from an altitude of 300 meters. At the time of release, both the plane and package are moving at 100 meters per second, directed at an angle of 20 degrees below the horizontal. How long is the package in the air? Find the magnitude and direction of the velocity of the package just before impact? Draw a sketch or diagram of the problem. Thank you for your help.

A car is traveling horizontally at 28.7 m/s at the moment it drives off the top of a cliff. The car strikes the ground 0.538 seconds after leaving the top of the cliff. Assuming air-resistance can be ignored, how tall is the cliff?

A truck, stolen by Dora the Explorer is initially stopped 10.0 m from the base of a building. Peppa pig is 22.0 m above the ground on the balcony of her office building. The truck begins to accelerate towards the building. One second after the truck moves, Peppa pig jumps off the balcony. Peppa pig, in an attempt to stop Dora the Explorer, times her fall perfectly and lands on the truck, which is 3.0 meters above the ground. What was the acceleration of the truck and its final velocity (assume constant acceleration)?
