Question

a body projected up vertically up with a velocity 10m/s reaches a height of 20m. If it is projected with a velocity of 20m/s,then the maximum height reached by the body?......

Answer 1

Using first case find angle of projection
H= usquare sinsquareQ / 2g
Hers u is 10 ms-1
H is 20m

Then calculate max. Height for the second case
Here u will be 20ms-1
Q is calculated in first case.

Hope you get your answer.
