Two golf balls are hit from the same point on a flat field. both are hit at an angle of 30∘ above the horizontal. ball 2 has twice the initial speed of ball 1.
if ball 1 lands a distance d1 from the initial point, at what distance d2 does ball 2 land from the initial point? (neglect any effects due to air resistance.)

the distance of second ball will be 4 times more than the distance of first ball.

Explanation:

Since both the balls are hit from ground level and reached again at ground then the horizontal distance covered by the ball must be equal to the range of projectile motion

As we know that range of projectile motion is given as

so here we can say that for the first ball is the speed is "v" then its distance on the ground will be

now for the other ball if the speed is double but the angle is same so we have

so the distance of second ball will be 4 times more than the distance of first ball.
