M1 and M2

A mass, m1, accelerates at 3 m/s2 when a force, F, is applied. A second mass, m2, accelerates at 1.0 m/s2 when F is applied to it.

  1. Find the value of the ratio m1/m2.
  2. Find the acceleration of the combined mass ( m1 + m2) under the action of the force, F.

A 50 slug car can accelerate from 0 to 50 ft/s while traveling 1000 feet. The car then stops, and a passenger gets in. Now the car can accelerate from 0 to 50 ft/s while traveling 1050 feet. What is the weight of the passenger?

Howard doesn't Move

Howard is standing in the middle of a skating rink (we'll assume no friction), and his four friends Alice, Bernie, Christopher, and David approach him from each of the four compass directions - north, east, south, and west, respectively.

Alice pushes on Howard with a force of x + 20 Newtons. Bernie pushes on him with a force of 2x + y Newtons. Christopher pushes on him with a force of 2x - y Newtons, and David pushes with a force of 5y Newtons.

Howard, though being pushed from all directions, does not move. Calculate the forces being applied in all four directions.

Car and Motorcycle
