Answer : The force exerted by the pump on the water is, 4533.33 N
Solution :
Power : It is defined as the work done in per unit time.
Formula used :
[tex]P=F\times V\\\\F=\frac{P}{V}[/tex]
where,
P = power = [tex]3.4\times 10^2watts[/tex]
V = velocity = [tex]7.5\times 10^{-2}m/s[/tex]
F = force
Now put all the given values in the above formula, we get the force exerted by the pump on water.
[tex]F=\frac{3.4\times 10^2watts}{7.5\times 10^{-2}m/s}=4533.33N[/tex]
Therefore, the force exerted by the pump on the water is, 4533.33 N
