By what numerical factor will the range increase if you launch the ball horizontally from a height which is four times greater than in the lab? Explain your answer.

Step 1

Let *v* be the horizontal velocity with which the ball is launched, *h _{1}* be the height in the lab,

Write the second kinematic equation of motion for the ball in the vertical direction.

Step 2

Write the second kinematic equation of motion for the ball in the horizontal direction and substitute the known values.

Step 3

Write the relation between both the heights.
