How much force is needed to accelerate a 1245 kg car at a rate of 4.25
m/sec^2?

In this experiment, you will use a track, a toy car, and some washers to explore newton’s first two laws of motion. you will make observations and collect data regarding the motion of these objects. in the space below, write a general scientific question that you will answer by doing this experiment.

Imagine that someone pushes one marble toward a motionless marble. would there still be action-reaction forces involved in the collision? how might the marbles’ motions be changed? ?

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