If under the action of force f1 20 n the body moves with an acceleration of 5 m / s2, then for imparting acceleration to this body a2 = 1 m / s

A body of mass m under the action of force F moves with acceleration a. The relationship between the quantities is generally described by the formula:

F = ma.

Find body weight:

m = F1 / a1 = (20 N) / (5 m / s ^ 2) = 4 kg.

Find the force required to give the body an acceleration of 1 m / s ^ 2:

F2 = a2m = 1 m / s ^ 2 * 4 kg = 4 N.

Answer: 4 N.
