A point on a wheel moves at 32π/9 radians per minute. How many seconds are required for the point to complete 7 revolutions?

The number of seconds required to complete 7 revolutions is 236.28 s.

Step-by-step explanation:

Given;

speed of the point on the wheel, ω = 32π/9 rad/min

number of revolutions made by the point, θ = 7 rev

The time taken for the point to make 7 revolutions is calculated as follows;

1 rev = 2π rad

Therefor, the number of seconds required to complete 7 revolutions is 236.28 s.
