Consider a particle launched at a horizontal velocity v0 from a height h above the ground. 1. Derive an expression for the time
it takes the projectile to strike the ground. Ignore air resistance.
1 answer:
Answer: 
Explanation: The time taken by the object to reach the ground depends up on the vertical velocity of the object.
The object horizontal velocity component only moves the object in forward direction and does not have any effect vertically
as the object is launched horizontally its initial vertical velocity is zero

the object experiences downward fall due to gravitational acceleration only since there is no air resistance
therefore a=g
the distance covered =s=h
now the kinematic equation could be used

In my opinion I think the answer is C you don't have to choose C
Answer:
Explanation:
If you look closely, force 1 does not reach 0.2 until 0.4 force 2 reaches 0.2 at about 0.2 - hope that made sense :P
