Question

all moves along a circle of radius 25 cm with a constant angular acceleration if the velocity of the particle is 80 metre per second at the end of the second evolution after motion has become the tension acceleration is​

Answer 1

Explanation:

Total distance travelled= 2πr× 2(for 2 revolution)

=S= 2×2π×20/π = 80m ...... (1)

.

.

Now by using the formulae

v^2 - u^2 = 2aS

(80)^2 = 2a80 .(from 1)

a= 80×80/2×80 = 40m/s^2
