Question

A golfer hits a ball at a speed of

v

at an angle of =30 degrees

above the horizontal. The ball lands on a green which is

elevated 7 m above the level at which the ball was struck.

The ball travels a horizontal distance of 112 m.

At what speed

v

was the ball hit?

Answer 1

let velocity= V₀

angle

given range= 112m

we know

the height reached by projectile

so the velocity of the ball is 33.8m/sec in three significant figure
