A truck moving at `72 kmh ^(-1)` carries a steel girder which rests on its wooden floor. What is the minimum time in which the truck can come to stop without the girder moving forward ? Coefficient of static friction between steel and wood is `0.5`.

Determine the maximum acceleration of the truck in which a box lying on the floor of its back will remain stationary, given that the coefficient of static friction between the box and truck's floor is 0.2.

In the masses of A and B are 10 kg and 5 kg . Calculate the minimum mass of C which may stop A from slipping Coefficient of static friction between block A and table is 0.2 .

Determine the maximum acceleration of the truck in which a box lying on the floor of its back will remain stationary , given that the coefficient of stastic friction between the box and trucks 's floor is 0*2 .

Find the distance travelled by a body before coming rest, if it is moving with a speed of 10ms^(-1) and the coefficient of friction between the ground and the body is 0.4 .

A body of mass 2 kg is moving on the ground comes to rest after some time. The coefficient of kinetic friction between the body and the ground is 0.2. The etardation in the body is

When a car of mass 1000kg is moving with a veocity of 20ms^(-1) on a rough horizontal road its engine is switched off. Hwo for does the car move before it comes to rest if the coefficient of kintic friction between the road and tyres of the car is 0.75 ? .

A car starts from rest at time t = 0 and it a-t graph is shown in figure. A coin is initially at rest on the floor of the car. At t = 1 s the coin begins to slip and it stops slipping at t = 3 s. The coefficient of static friction between the floor and the coin is (g = 10 m/ s^2 )

A car begains from rest at time t = 0 , and then acceleration along a straight track during the interval 0 lt t le 2 s and thereafter with constant velocity as shown in figure in the graph. A coin is initially at rest on the floor of the car. At t = 1 s , the coin begains to slip and its stops slipping at t = 3 s . The coefficient of static friction between the floor and the coin is (g = 10 m//s^(2))

A man of mass 75 kg is pushing a heavy box on a flat floor. The coefficient of kinetic and static friction between the floor and the box is 0.20 , and the coefficient of static friction between the man's shoes and the floor is 0.80 . If the man pushes horizontally, what is the maximum values (in kg ) of the box he can move?
