Question

speed of circle path body​

Answer 1

Answer:

if the speed is constant then change is kinetic energy is zero corresponding work done will be zero. the forces applying on the body are in radial direction and movement of body is tangential (angle between force and displacement is 90∘) sot the total work done by forces will be zero.

Answer 2

Answer:

1 metre per second

Step-by-step explanation:

In the simplest case the speed, mass and radius are constant. considered the body at 1 kilometre , moving in a circle of radius one metre ,with an angular velocity of one radian per second .the speed is 1 metre per second .the inward acceleration is 1 metre per square second v2/r.
