Sand is being dropped on a conveyor belt at the rate of M kg//s . Tne force necessary to keep the belt moving with a constant velocity of v m//s will be:

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?

Two wheels are connected by a belt.The radius of larger wheel is three times that of the smaller one.What is the ratio of the angular velocity of the two wheels i.e. (omega_(b))/(omega_(s)) ?

Wheel A of radius r_(A)=10cm is coupled by a belt C to another wheel of radius r_(B)=25 cm as in the figure. The wheels are free to rotate and the belt does not slip . At time t=0 wheel A increases it's angular speed from rest at a uniform rate pi//2 rad //sec^(2) Find the time in which wheel B attains a speed of 100 rpm [ Hint : v_(A)=v_(B)]
