Question

8. A stone is projected with velocity 50 m/s at angle 60° to
the horizontal. What will be the speed of stone at the time
when it makes angle 30° with horizontal?
And-28.8 m/s
Note-ALL WRONG ANSWERS WILL BE REMOVED NO SPAMS

Answer 1

Answer:

ANSWER

At the highest point, the stone has only horizontal velocity but not vertical velocity.

Initial horizontal velocity of stone u

x

=ucosθ=50×cos60=25 m/s

Since, there is no acceleration in the horizontal direction. so horizontal velocity of stone remains constant with time.

Thus, speed at the highest point V

x

=
