A golfer pulls on the eighteenth green at a distance of 5.0m from the hole. The ball rolls straight. In the positive direction, but overshoots the hole by 1.2m. The golfer then putts back to the hole and sinks the putt for par. What is the displacement of the ball?

Explanation:

The initial position of the ball = - 5 .0 m from the hole .

It is negative because , direction towards the hole is positive so direction from the hole will be negative .

Final position of the ball = 0 m from the hole .

Displacement of the ball = Final  position - Initial  position

= 0 - ( - 5 ) = 5 .0 m

Displacement = + 5 m

true tan speed = ang vel x radius
