Question

A body thrown vertically up reaches a maximum height of $50m$. Another body with double the mass thrown up with double the intial velocity will reach a maximum height of

• A. $100m$
• B. $200m$
• C. $400m$
• D. $50m$

Answer 1

The correct option is B $200m$

Irrespective of mass $H_{max}=u^2/2g=50m$

if we double the initial velocity $u$ then $H_{max}$ will get $4$ times means $200m$ .
