A box rests on top of a flat bed truck. The box has a mass of m = 20 kg. The coefficient of static friction between the box and truck is mu_s = 0.86 and the coefficient of kinetic friction between the box and truck mu_s = 0.67. The truck accelerates from rest to v_f = 19 m/s in t = 12 s (which is slow enough that the box will not slide). What is the acceleration of the box?...
m A box rests on top of a flat bed truck. The box has a mass of m = 16 kg. The coefficient of static friction between the box and truck is is = 0.82 and the coefficient of kinetic friction between the box and truck is Hk = 0.64. 1) The truck accelerates from rest to Vp = 19 m/s in t = 13 s (which is slow enough that the box will not slide). What is the acceleration...

A box of mass 40 kg is initially at rest on a flat floor. The coefficient of kinetic friction between the box and the floor is µk = 0.40. A woman pushes against the box with a force of 250 N that makes an angle of 30° with the horizontal until the box attains a speed of 1.0 m/s. (a) What is the change of kinetic energy of the box? (b) What is the work done by the friction force...
42.0 kg boy is sliding on a horizontal, frictionless surface with an initial momentum towards east. His momentum has magnitude 87.0 kg⋅m/s. Starting at 0 s, a net force with magnitude F=( 8.00 N/s )t and direction due west is applied to the boy. a)At what value of t does the boy have a westward momentum of magnitude 61.0 kg⋅m/? b)How much work has been done on the boy by the force in the time interval from t=t= 0 s...

A box (350 kg) sits inside the trailer of a semitruck traveling at a speed of 15 m/s (~ 33 mph). Suddenly, a car in front of the truck stops in the road. The driver of the truck hits the brakes to bring the truck to a stop. Assume that the coefficient of static friction µs = 0.7 between the box and the floor of the trailer. Assume g = 10 m/s2. When the truck is slowing down, what is...
