Question

A point P moves in counter-clockwise direction on a circular path as shown in the

figure. The movement of P is such that it sweeps out a length s = t3 + 5, where s is in

metres and t is in seconds. The radius of the path is 20 m. The acceleration of P when t =

2 s is nearly​

Answer 1

Answer:

2=3+5=8+2=10

the radius =20

so 20+10=30

s= 30
