In The Figure Below Motor M Delivers A Constant Force And Box B Starts From Rest At T 0 The Mass Of Box B Is 3 Kg And 1 (23.74 KiB) Viewed 49 times

In the figure below motor M delivers a constant force and box B starts from rest at t = 0. The mass of box B is 3 kg and the coefficient of kinetic friction between the box and the plane is 0.25. You observe that the crate moves a distance of 2.7 m up the plane during the first 3.0 s. The efficiency of the motor is 0.80. M B 30° a) Calculate the acceleration of the box. b) Calculate the work done by the friction force during the first 3.0 s. c) Calculate the output force delivered by the motor. d) Calculate the power input to the motor at t = 3.0 s.
