The coefficent of static friction between the floor of a truck
and a box resting on it is 0.35. The truck is traveling at 81.3
km/hr. What is the least distance in which the truck can stop and
ensure that the box does not slide?
Homework Answers
acceleration till which the box friction can withstand
a = ug = 0.35* 9.8 = 3.43 m/s^2
now, using 3rd equation of motion
d = v^2/ (2 a)
d = (81.3* 5 / 18)^2 / ( 2* 3.43)
d = 74.345 m

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...

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?...
