Question

a stone is projected with a velocity 20√2m/s at an angle 45 to the horizontal at the average velocity of stone during it's motion from starting point to its maximum height is​

Answer 1

Explanation:

average velocity is given by

time

displacement

displacement till highest point will be (

2

R

,H) in horizontal and vertical direction respectively.

As given V=20

, θ=45

then H=
