A hopper drops gravel at a rate of 15 kg/s onto a conveyor belt moving at a constant speed 4m/s. If the output power must motor have in order to drive the conveyor belt is 48 k. Find the value of k.

Answer:

Solution:

$F = u \frac{d m}{d t} = 4 \times 15 = 60 N$

$P = F v = 60 \times 4 = 240 W = 48 k \Rightarrow k = 5$ . Answer 5.
