A conveyor belt is designed to transport packages of various weights. A 10-kg package has a coefficient of kinetic friction . If the speed of the conveyor is 5 m/s, and then it suddenly stops, determine the distance the package will slide on the belt before coming to rest.

Question 1

A jet airliner with a mass of m_A kg has three working engines, each of which produces a constant thrust of T kN during its take-off roll.

Consider the runway from A to B as shown in the figure, which has an uphill incline of θ.

Assume a rolling friction coefficient equal to 0.

Select the correct free body diagram for the airliner from the options below. Align the coordinate system such that the x-direction is parallel to the runway and the y-direction is normal to the runway.

Calculate the frictional force on the crate that is being pulled by a force entirely in the horizontal direction.

The mass of the grate is 100kg and the coefficient of kinetic friction between the crate and the ground is .
