Questions
A body is projected at an angle of 30° with the horizontal and with a speed of 30 ms-1. What is the angle with the horizontal after 1.5 s ? (g = 10 ms-2)
detailed solution
Correct option is A
The time of flight is given byT=2usinθg=2×30×1/210=3sThus, after 1.5 s, the body will be at the highest point. So the direction of motion will be horizontal after 1.5 s, the angle with the horizontal is 0°.Talk to our academic expert!

Assertion : When the velocity of projection of a body is made n times, its time of flight becomes n times.
Reason : Range of projectile does not depend on the initial velocity of a body.
