Question

Physics
An athelete throws discuss from rest to a final angular velocity of 15 rad/s in 0.27s before
releasing it. During acceleration, discuss moves in a circular arc of radius 0.810m. Acceleration
of discuss before it is released is.
Medium​

Answer 1

Answer:

45 m/s²

Explanation:

We know linear velocity v = ωr

here ω = angular velocity = 15 rad/s and r = 0.810 m

Thus v = 15 × 0.810 = 12.15 m/s

also we know that

$a = \frac{v - u}{t}$

where v = final velocity , u = initial velocity & t = time

$a = \frac{12.15 - 0}{0.27} \\ a = \frac{12.15}{0.27} = 45 \:{m} s^{ - 2}$

Hope you understand it
