Question

A partiele travels in a circle of radius 20 cm at a speed that unifor
increases. If the speed changes from 5.0 m/s to 6.0 m/s in 2.0 5,
the angular acceleration.
1) 9.5 rad/s2 2) 7.8 rad/s2 3) 5.7 rad/s2 4) 2.5 rad/s2
​

Answer 1

Explanation:

r=20/100

=0.2

v=6

u=5t=2

alpha=a/r

=0.5/0.2

=2.5
