A person weighing 935. N rides in an elevator that has a downward acceleration of 1.26 m/s2. What is the magnitude of the force (in N) of the elevator floor on the person?

A block of mass 19.00 kg slides down an inclined surface at an angle 0 = 65.0° with speed v. The surface and block have a coefficient of kinetic friction my = 0.15. Determine the acceleration of the block down the inclined surface. 40.96 m/s^2 27.93 m/s^2 15.71 m/s^2 8.26 m/s^2

A woman pulls a cloth out from under a 200 g bowl sitting on a table. The bowl is 30.0 cm from the far edge of the cloth, and the cloth exerts a friction force of 0.125 N on the bowl. Assume the cloth is pulled with a constant horizontal acceleration of 2.80 m/s2. What distance (in m) does the bowl travel relative to the top of the table? (Assume the cloth moves in the +x-direction and notice that it moves more than 30.0 cm relative to the top of the table.)

A 5-kg block is set into motion up an inclined plane (30°) with an initial speed of 8.0 m/s. There is friction between the block and the plane. The block comes to rest after traveling 3.0 m along the plane. Define the positive x-direction to be down the ramp.
