Question

a ball of mass mass m kg is thrown vertical upwards . another ball of mass 2m kg is thrown at angle X with the vertical. both stays in air for the same period the height reached are inthe ratio​

Answer 1

Explanation:

Time of flight in case (1) = case (2)

g2V1=g2V2sinθ⇒V1=V2sinθ

max height reacted by (1)=2gV12=H1

max height reacted by (2)=2g(V2sinθ)2=H2

⇒H1=H2.
