Question

if water falls on the plate with velocity 20m/s at rate of 0.5kg/s ,find the force on the plate

Answer 1

Answer:

1. a=20 .m=0.5. f=ma=20*0.5=10N

Answer 2

Answer:

The force on the plate is `10N.

Explanation:

Here we have been given that water falls on a plate with velocity 20m/s at the rate of 0.5kg/s and we are asked to find the force on the plate. For doing so first of all we have to write what is given in the question and what we have to find as shown below:

Given:

velocity of water = 20m/s

rate of flow of water dm/dt= 0.5kg/s

To find:

Force of water F= v(dm/dt)

                        F= 20(0.5)

                        F= 10N

Hence the force on the plate is `10N.
