Question

a train of mass 100 tones is moving with a uniform speed of 2 m/s calculte the amount of energy possesed by the train

Answer 1

Answer:

Explanation:

MASS OF TRAIN = 100 TONEE

1000 KG = 1 TONNE

X KG = 100 TONNE

X = 10⁵ KG.

MASS OF THE TRAIN = 10⁵KG

VELOCITY = 2 M/S.

ENERGY ATTAINED BY THE TRAIN = KINETIC ENERGY

KINETIC ENERGY = 1/2 MV²

                               = 1/2*10⁵*4

                               = 2*10⁵ J

                               = 200 KJ.

HOPE THIS HELPS.
