A Ping-Pong ball moving east at a speed of 4 m/s, collides with a stationary bowling ball.  The Ping-Pong ball bounces back to the west, and the bowling ball moves very slowly to the east.  Which object experiences the greater magnitude impulse during the collision?

A 25-kg crate is pushed across a frictionless horizontal floor with a force of 20 N, directed 20◦below the horizontal. The acceleration of the crate is:

A flywheel of radius 25.0 cm is rotating at 655 rpm. Find its angular displacement ( in rad ) in 3.00 min.

A child, riding on a large merry-go-round, travels a distance of 3000 m in a circle of diameter40 m. The total angle through which she revolves is:

A flywheel of radius 25.0 cm is rotating at 655 rpm. Express its angular speed in rad /s

A normal O2 saturation percentage should be:

A piece of equipment that measures the gases (CO2) in the blood using a heated sensor that is placed on the skin. 

Put a pipe over the end of a wrench when trying to turn a stubborn nut on a bolt, to effectively make the wrench handle twice as long, you’ll multiply the torque by

A 0.125 kg frozen hamburger patty has two forces acting on it that determine its horizontal motion. A 2.30 N force pushes it to the left, and a 0.800 N force pushes it to the right. (a) Taking right to be positive, what is its acceleration?

Two identical charges, 2.0m apart, exert forces of magnitude 4.0N on each other. The value of either charge is: (K = 8.9 x10 9 N m2/C2)
