Explanation:
From the question we are told that:
Initial Speed
Time
Angle
Generally the Newton's equation for motion is mathematically given by
Answer:
Explanation:
Given
inclination
initial speed
Point of release is 45 m above the ground
Considering stone to be a projectile, so time taken by projectile for its zero vertical displacement is
Now after completing zero vertical displacement , stone needs to travel another 45 m in downward direction with initial speed u=20\sin 30
where,
thus total time time required is
vertical velocity just before hitting
Horizontal velocity
Net velocity Just before hitting
