Question

A smooth sphere(10 kg) rolls on a smooth curved surface from point a with speed 10m/s. it reaches points through



b.find total energy ata

Answer 1

Given conditions ⇒

Velocity = 10 m/s.

Mass = 10 kg.

Using the Formula,

K.E. = 1/2mv²

⇒ K.E. = 1/2 × 10 × 10²

⇒ K.E. = 5 × 100

⇒ K.E. = 500 J.

Since, The Potential energy will be zero in this case, therefore, Total energy will be equal to the kinetic energy.

Hence, the total energy of the body at point A is 500 J.

Hope it helps.
