Question

A stone is projected from the ground with velocity 25m/s . After 1.25 sec,it is at the highest point of its trajectory . The angle of the projection of stone is​

Answer 1

Explanation:

let us assume ,(u=vel) g=10 and A is the angle

time to reach highest point is=usinA/g

usinA/g=1.25

as given u=25m/s

25sinA=12.5

sinA=1/2

angle A=60°
