Question

What is the engine power of a car with retarding force 500Nmoving at constant speed 20ms¯²

Answer 1

Given:-

What is the engine power of a car with retarding force 500Nmoving at constant speed 20ms¯²

Find:-

retarding force 500Nmoving at constant speed 20ms¯²?

Solution:-

Acceleration,

$\sf \: a = \frac{vfinal -vinitial }{time}$

Therefore,

$\sf \: 2m/s ^{2} = \frac{vfinal - 2m/s ^{2} }{5s}$

$\sf \: vfinal = 10m/s$
