Question

A particle of mass 2 kg is moving in circular path with constant speed 20 m/s. The magnitude of change in velocity
when particle travels from A to P will be​

Answer 1

Answer:

40 m\s

Explanation:

magnitude of change in velocity = change in mass * change in velocity

SINCE MASS IS CONSTANT;

magnitude in change in velocity ( delta v ) = m * v(constant velocity)

(delta v) = 2kg * 20m\s

=40 m\s

hence delta v =  40  m\s
