At what height h above the ground does the projectile have a speed of 0.5v?

Question

Question:

At what height h above the ground does the projectile have a speed of 0.5v?

Answer:

Shot Motion

Shot movement is a movement wherein an article tossed at an edge goes in an illustrative way to arrive at the ground level. The main speeding up is vertical way which is quickening because of gravity.

Explanation:
Given Data
• The beginning speed of the shot is: v
• The speed at stature h is: 0.5v
Compose the condition of movement for speed.
vf=vi−gt

Here, the underlying speed of the shot is vi, the last speed of the shot is vf, the increasing speed because of gravity is g and the time taken is t
Substitute the known qualities in above articulation.
0.5v=v−gt
gt=0.5v
t=0.5v/g

Compose the condition of movement for stature.
h=vit−1/2gt2
Substitute the incentive in above articulation.
h=v(0.5v/g)−1/2g(0.5v/g)2
h=0.5v2/g−0.25v2/2g
h=0.375v2/g
Hence, the tallness over the ground at which shot have speed 0.5v is 0.375v2/g
