Question

a car of mass 500 kg approaching a hill. it moves up the hill with uniform speed. ignore the air friction and take the value of 10 m/-2 how much work is done in moving the car up the hill​

Answer 1

Answer :-

Given :-

Mass (m) = 500 Kg

Height (h) = 10 m

Gravitational field strength (g) = 10 N/kg

To find :-

Work done (W)

Solution :-

Work done:

• mgh

=> 500 × 10 × 10

=> 50000 J

or 5 × 10⁴ J

∴ The work done in moving the car up the hill is 5 × 10⁴ J.
