In this lab you will use a cart and a track to explore Newton’s second law of motion. You will vary two different variables and determine how each one affects how quickly the cart moves along the track. In the space below, write a scientific question that you can answer by doing this experiment.

What is relative velocity? in which condition is relative velocity known by adding the velocity of the first body and that of the second body

If angle "a" is 25°, angle "b" is: a) equal to angle c b) less than angle c c) greater than angle c

A1-lb collar is attached to a spring and slides without friction along a circular rod in a vertical plane. the spring has an undeformed length of 5 in. and a constant k =25 lb/ft. knowing that the collar is released from being held at a determine, the speed of the collar and the normal force between the collar and the rod as the collar passes through b.
