A box with mass M=10 kg is on the back of a trailer and it has the coefficient of friction μ=0.2 with the back of the trailer. a) What is the maximum possible acceleration a=? of the truck such that the box does not slip on the back of the truck? b) If the truck moves with acceleration A=100 m/s such that the box slips on the back of the truck, with that acceleration will the box move on the...
QUESTION 3 The 1500-kg rear driving truck reaches a speed of 50 km/h from rest in a distance of 60 m up the 10-percent incline with constant acceleration. Calculate the normal force under each pair of wheels and the effective coefficient of friction between the tires and the road during this motion (Hints: the driving force from the friction of the rear wheels, not from front wheels).

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...
2500 kg a = 2 m/s? 1.5 m FIG. 05 N A 2500 kg loaded truck starts from rest with a constant acceleration of 2 m/s on a horizontal road. The truck is a rear-wheel drive truck. Find : a) The normal reactions on the front and rear wheels of the truck. b) If the road surface is dry and the coefficient of friction between the tyres and road u = 0.8 and the coefficient of rolling resistance is 0.02,...
Part 2 After reaching the top of the incline, the box of mass 1 kg is released, and allowed to slide back down the hill of incline angle 0 20 At the halfway point, the surface of the incline becomes rough, and friction becomes important The coefficients of friction between the box and hill are μ-: 0.7 and μ.-0.5. 0 20 D. Draw a free body diagram for the object as it moves down the incline as it encounters the...
