The period of motion is 0.52 seconds

Solution:

Given that,

speed = 48 m/s

radius = 4 m

Find the circumference of circle

$C = 2 \pi r\\\\C = 2 \times 3.14 \times 4\\\\C = 25.12$

Find the period of motion

$V = \frac{2 \pi r}{T}\\\\48 = \frac{25.12}{T}\\\\T = \frac{25.12}{48}\\\\T = 0.5233 \approx 0.52$

Thus period of motion is 0.52 seconds
