19. If two bodies A and B are projected upwards such that the velocity of A is double the velocity of B, then the height to which the body A will rise will be…………………….the height to which body B will rise

Answer 1

Answer:

4 times higher than body B

Explanation:

Use the formula h = u²/2g, where

initial velocity = (u)m/s

Acceleration due to gravity = (g)m/s²

Height = (h)m

let initial velocity of B = u

initial velocity of A = 2u

Thus, Height(a)= h = 4u²/2g

         Height(b)= h = u²/2g

Ratio of heights = 4u²/2g : u²/2g

                          => 4 : 1

Thus, it will go 4 times higher.
