Question

A body, thrown upwards with some velocity, reaches the maximum height of 20m. Another body with double the mass thrown up, with double initial velocity will reach a maximum height of

• A. 200 m
• B. 16 m
• C. 80 m
• D. 40 m

Answer 1

Answer: (C)

80 m

Answer 2

Mass does not affect on maximum height.

$H = \frac{u^{2}}{2g} \Rightarrow H \propto u^{2}$, So if velocity is doubled then height will become four times. i.e.$H = 20 \times 4 = 80m$
