Question

if a particle in UCM has linear speed 5 m/s and angular speed 2 rad/s, what is the magnitude of its centripetal acceleration​

Answer 1

Answer:

Centripetal acceleration= 10 m/s^2

Explanation:

angular velocity=linear velocity*radius

therefore, 2=5*r

or, r=2.5m

now angular acceleration = omega^2 * r

=2*2*2.5

=10 m/s^2
