Question

a stone is thrown with the help of a sling with initial velocity 0 at an angle 0 from the horizontal

Answer 1

Answer:

The horizontal component of the velocity will be constant during the projectile motion. Horizontal component of the initial velocity, u  

x

​  

=v  

0

​  

cosθ  

0

​  

. Horizontal component of the velocity when the particle makes an angle θ with horizontal, v  

x

​  

=vcosθ.

Hence, vcosθ=v  

0

​  

cosθ  

0

​  

⇒v=  

cosθ

v  

0

​  

cosθ  

0
