Question

Q.1 A vehicle of mass 1500 kg climbs up a hill 200 m high. It then moves
on a level road with a speed at 30 m/s Calculate the potential
energy gained by it....​

Answer 1

Answer:

so you first multiply the above kg and m then after divide it by time.

Answer 2

Potential energy gained = 3 x 10⁶

Explanation:

The potential energy is due to the position of body .

As the body of mass 1500 kg climbs up to height 200 m

Its potential energy increases by  P.E = m g h

here m is the mass of body

g is the acceleration due to gravity

h is the height of body

Thus P.E = 1500 x 10 x 200 = 3 x 10⁶ J

When it moves on level road , there is increase in K.E but P.E remains the same .

Therefore potential energy gained = 3 x 10⁶ J
