Expert Answer

Step 1

Let v be the horizontal velocity with which the ball is launched, 1 be the height in the lab, h2 be the height in actual, R1 be the range of the ball when it is launched in the lab, R2 be the range when it is fired in actual.

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

Physics homework question answer, step 1, image 1

Step 2

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

Physics homework question answer, step 2, image 1

Step 3

Write the relation between both the heights.
