Sand drops from a stationary hopper at the rate of 5 kg/s falling on a conveyor belt moving with a constant speed of 2 m/s. What is the force required to keep the belt moving and what is the power delivered by the motor moving the belt?
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
F ext = 10N; P = 20 watt.
Sol. F = μ 
= 2×5 = 10 N Ans.
P = F.v. = 10×2 = 20 W Ans.
