A baseball is thrown a distance of 20 meters what is its speed if it takes 0.5 seconds to cover the distance?

Two horses leave the starting gate at the beginning of a 2000 m long race. The brown horse has an acceleration of 2.2 m/s2 and a top constant speed of 18 m/s. The black horse has an acceleration of 1.7 m/s2 and a top constant speed of 20 m/s.

A rock is dropped from a sea cliff, and the sound of it striking the ocean in heard 3.0. s later. If the speed of sound is 340m/s, how high is the cliff?

A 36.5 kg box initially at rest is pushed 4.30 m along a rough, horizontal floor with a constant applied horizontal force of 150 N. If the coefficient of friction between box and floor is 0.300, find the following.

3 In a television tube, an electron starting from rest experiences a force of 4.0 * 10-15 N over a distance of 50 cm. The final speed of the electron is (do not worry about relativistic effects) :
