Question

A body is proiected with a speed u at angle to the horizontal to have maximum range at the highest point the velocity is
a.zero
b.u
c.u/root2
d.u root2​

Answer 1

Answer:

Velocity at highest point has two components:

1) vertical component=0

2) horizontal component = ucostheta

Hope it helps you...!!!!

Answer 2

Answer:

Maximum range means, angle=45`

Maximum range means, angle=45`total velocity=vertical velocity (0) +horizontal velocity(Vcos45)

Maximum range means, angle=45`total velocity=vertical velocity (0) +horizontal velocity(Vcos45)=V√2
