Use this free body diagram to you find the magnitude of the force f1 needed to keep this block in static equilibrium. a. 15.3 newtons b. 36.3 newtons c. 63.5 newtons d. 95.5 newtons

The motor m applies a time-varying force of f (200 t) n, where t is in seconds. box b with mass 200 kg starts from rest, and the coefficients of kinetic and static friction are 0.2 and us 0.3 the acceleration due to gravity is g 9.8 m/s2 b 300 a) find the time ' when the box starts to move. b) calculate the speed of the crate at 3 s c) calculate the power delivered by the motor at t 3 s
