A golf ball is struck a mighty blow from a driver, lauching it at an angle of θ=10.1o.

The golf ball has been constructed to current professional standards for mass and size:

mB=45.9g and RB=21.5mm.

The impact between the club and the ball may be crudely modelled as a uniform (average) force of F=43kN for a duration Δt=43 μs through a line of action such that b=3.27mm.

Hint: You may assume the impact is sufficiently brief that the ball does not change orientation during the impact.

a) What is the magnitude of the angular velocity of the ball ( ω) immediately after impact (knowing vG having value 40.28)?
b) What is the magnitude of the velocity of the point A ( vA), on top of the ball, immediately after impact?

I am able to find the angular velocity but am unsure what is needed to find the velocity at point A as is needed for part c.
