Question

If the mass of a car is 1500 kg, what work is to be done to increase the velocity of the car from 18 km/h

Answer 1

Answer:

HERE YOU GO~

---------------------

GIVEN ~

(i) m = 1500 kg

(ii) v = 18 km/h = 5 m/s

_______________________________________

TO FIND ~

work done = ?

_______________________________________

SOLUTION~

As we know ~

Work done = kinetic energy of the body

K.E = 1/2 × m × v^2

K.E = 1/2 × 1500 × 5^2

K.E = 750 × 25

K.E = 18750 J

HOPE THIS YOU.......

THANKS.......
