Question1

A child slides down a slide with a 31 degree incline, and at the bottom her speed is precisely one-third what it will have been if the slide had been frictionless. Compute the coefficient of kinetic friction between slide and child.

Question2

Two asteroids, drifting at constant velocity, collide. The masses and velocities of the asteroids before the collision are indicated.

Throughout the collision, is the magnitude of the force of asteroid A on asteroid B greater than, less than, or equal to magnitude of the force of asteroid B on asteroid A?

Mass A= 500 kg Velocity of A= 20 m/s

Mass B=250kg Velocity of B= 10m/s
