a 38 N horizontal force pushes on a 3.7 Kg mass resting on a horizonal surface. The surface exerts a friction of 22 N against the motion. The acceleration of the 3.7 kg Mass is
According to Newton's Second law of motion:
Since friction is an opposing force we have Fnet =38 - 22 = 16 N
Given mass = 3.7 kg, then acceleration is given by:

A mass of 12 kg is resting on a horizontal surface without friction. A force of 107 Newtons is applied in the +x direction, a force of 13 Newtons is applied in the -x direction, and a force of 11 Newtons is applied in the -y direction (downward). What is the acceleration of the mass in m/s2? If in the -x direction, include a negative sign.
