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.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
