Answer:
60m/s
Step-by-step explanation:
In this problem problem, it's expected of us to determine the linear velocity of the ball.
Given data
Angular velocity ω=40.0 rad/s
Radius r=1.5m
Velocity v=?
But we know that the expression relating angular velocity and linear velocity is given as
v=ωr
Now Substituting into the expression and solving for v we have
v=40*1.5
v=60m/s
Therefore the velocity of the ball is 60m/s
