A flexible drive belt runs over a frictionless flywheel (see Figure). The mass per unit length of the drive belt is 1 kg/m, and the tension in the drive belt is 10N. The speed of the drive belt is 2m/s. The whole system is located on a horizontal plane. Find the normal force (in N) exerted by the belt on the flywheel.

A motor drives a belt at a constant velocity of v m*s^(-1) . If m kg of sand fall on the belt per second ,what is the rate of work done by the force exerted by the belt on the sand ?

Two uniform cylinders, each of mass m = 10 kg and radius r = 150 mm, are connected by a rough belt as shown. If the system is released from rest, determine the tension in the portion of the belt connecting the two cylinders.

In an industry a 300 kg crate is dropped vertically from a packing mechine onto a conveyor belt moving at 1.2 m//s The coefficient of kinetic friction between belt and crate is 0.4 After a short time, slipping between the belt and the crate ceases and the crate then moves along with the crate ceases and the crate then moves along with the belt . For the period of time during which the crate is being brought to rest relative to the belt, calculate, for a reference frame (a) the kinetic energy supplied to the crate (b) the magnitude of the kinetic frictional force acting on the crate, the magnitude of energy supplied by the motion (c) Why are the answers to (a) and (c) different

Ona long horizontally moving belt, a child runs to and fro with a speed 9 km h^(-1) (with respect to the belt) between his father and mother located 50m apart on the moving belt. The belt moves with a speed on the moving belt. The belt moves with a speed of 4 km h^(-1) . for an observer on a stationary platform outside, what is the (a) Speed of the child running in the direction of motion of the belt? (b) speed of the child running opposite to the direction of motion of the belt? (c ) time taken by the child in a and b? which of the answers after if motion is viewed by one of the parents?

Sand drops fall vertically at the rate of 2 kg/sec on to a conveyor belt moving horizontal with a velocity 0.2 m/s. Then the extra force required to keep the belt moving is
