Question

32. The equation of angular displacement in a circular
motion of radius r at time t is given by 0 = kt + c Where
k and c are constants. The centripetal acceleration is
given by ...
a) rk b) rk c)r^2k^2
d) r^2k
​

Answer 1

Answer: 0 = kt + c

Differentiate it

w is angular velocity

w = k

Angular velocity = velocitu/ radius

w = v/r

k = v/r

v = kr

Centripetal acceleration = v^2/r

= k^2r^2/r

= k^2r

Or

= rk^2
