Answer:
Explanation:
height lost h = 300 sin60
= 259.8 m .
gravitational potential energy = mgh
= 5000 x 9.8 x 259.8
= 1273 x 10⁴ J
Kinetic energy
= 1/2 mv²
= .5 x 5000 x 60²
= 900 x 10⁴ J
there is loss of kinetic energy = 373 x 10⁴ J.
This loss in energy is due to kinetic friction that came into action when the sled slipped downwards.
The lost energy is converted into heat energy or thermal energy.
