Question

4. The linear acceleration (a) of a body rotating along a circular path of radius (r)
with an angular acceleration of a rad/s2, is​

Answer 1

Answer:

a = α.r

Explanation:

cuz angular acceleration is the product of angular displacement and radius

angular distance is "a" and radius "r"

angular acceleration(a) = angular distance by with radius

so α=a/r

i.e a = α.r

Answer 2

Answer:

Rad s3,is body rotation
