2. Jeremy throws a discus at the track and field competition. He throws it with an upward speed of 10 m/s and a horizontal speed of 35 m/s. Calculate how far Jeremy throws the discus. (Hint: figure out
the time of the throw first).

Arod of some material 0.20 m long elongates 0.20 mm on heating from 21 to 120°c. determine the value of the linear coefficient of thermal expansion [in (degrees c)^-1] for this material.

A1,700kg car is being used to give a 1,400kg car a push start by exerting a force of 140n the impulse on the smaller car during the 30.0s of contact is +670kg*m/s. what is the impulse of the smaller car on the larger car? -814 kg*m/s 0kg *m/s -670kg*m/s -550kg*m/s

How is zig zagging a form of acceleration?
