At what height h above the ground does the projectile have a speed of 0.5v?
Express your answer in terms of v and the magnitude of the acceleration of gravity g.
It is given that,
Speed of the projectile is 0.5 v. Let h is the height above the ground. Using the first equation of motion to find it.
Initial speed of the projectile is v and final speed is 0.5 v.
g is the acceleration due to gravity
Let h is the height above the ground. Using the second equation of motion as :
So, the height of the projectile above the ground is:
Hence, this is the required solution.
