a zookeeper is trying to tranquillize a gorilla that has escaped they fire a dart vertically with a velocity of 15m/s from a height of 2 m the monkey is 20m away by what distance will the dart fall short

You are driving in Canada where the distances are marked in kilometers. The sign says that you are 153 km from Ottawa. You are traveling at a speed of 61.0 mi/h. How long will it take you to reach Ottawa?

A long string is wrapped around a 6.0-cm-diameter cylinder, initially at rest, that is free to rotate on an axle. The string is then pulled with a constant acceleration of 1.9 m/s2 until 1.3 m of string has been unwound. If the string unwinds without slipping, what is the cylinder's angular speed, in rpm, at this time?

On the Apollo 15 space mission, Commander David R. Scott verified Galileo's assertion that objects of different masses accelerate at the same rate. He did so on the Moon, where the acceleration due to gravity is 1.62 m/s2 and there is no air resistance, by dropping a hammer and a feather at the same time. Assume they were 1.25 meters above the surface of the Moon when he released them. How long did they take to land?

a pump ejects 12000 kg of water at speed of 4 m/s in 40 seconds. find the average rate at which the pump is working.

A bead slides on the frictionless wire as shown in the figure attached. If the speed of the beead is 2.0 m/s when its at A, how fast will the bead be going at point B and at point C?

A softball is fouled off with a vertical velocity of 30m/s and a horizontal velocity of 15m/s. Assumed starting and stopping at height of 0m. How fast is the ball traveling horizontally 1.5sec after if is fouled off? How high does the softball travel? How far horizontally does it go?

What speed must you toss a ball straight up so that is takes 4.5 S back to get back to you? How high would it go?

10 kg block, with 20 cm × 20 cm × 40 cm sides, is laying down on it's shortest edge. How much work (A) do we need to do, to spin it over the edge?
