Answer:
height is 4 times
Explanation:
speed of ball hit by Luis is u
speed of ball hit by Ron is 2u
Let the maximum height traveled by the ball hit by Luis is h and by the ball hit by Ron is h'
At maximum height, the final velocity of ball is zero in both the cases.
Use third equation of motion, we get
For Luis :
.... (1)
For Ron :
.... (2)
Divide equation (2) by equation (1), we get
h' = 4 h
Thus, the statement of third student is wrong.
