Mr. E is running at 15m/s and slides to a stop in 0.8s (he's a baseball player). Write two equations for: What was his average acceleration while stopping? And: How far did he travel while stopping?
The position of an object as a function of time is given by x = At2 - Bt + C, Find the instantaneous velocity and acceleration as functions of time
A coin with a diameter of 2.30 cm is dropped on edge onto a horizontal surface. The coin starts out with an initial angular speed of 15.5 rad/s and rolls in a straight line without slipping. how far does the coin roll before coming to rest

A golfer putts a 46-g ball with a speed of 3.0 m/s. Friction exerts a 0.020 N retarding force on the ball, slowing it down. Will the putt reach the hole
A cart with mass 470 g moving on a frictionless linear air track at an initial speed of 1.8 m/s undergoes an elastic collision with an initially stationary cart of unknown mass. After the collision, the first cart continues in its original direction ..
Assume that electrons are the charge carriers and the conduction electron density is 2.35 x 10^23/ m^3. then calculate the electron drift speed in the wire.
