Question

two bodies are thrown vertically upwards with their initial velocity in ratio 2:3 the ratio of maximum height attained will be?

Answer 1

say the velocity of the first particle is u1.
say the velocity of the second particle is u2.
u1/u2=2/3
u1=2u2/3
The velocity at the maximum height will be 0.
0=u1^2-2gh1
u1^2=2gh1
u2^2=2gh2
