In projectile motion Why is the vertical component of velocity zero at the highest point of the trajectory?
Just before it reaches the highest point, the vertical component of velocity is upward.Just after it passes the highest point, the vertical component of velocity is downward.There's no way you can change from an upward velocity to a downward velocity smoothlywithout velocity being zero at some instant. A.True.
What makes a thrown upwards body to stop for some few seconds before desendeing down?
It DOES NOT stop for a 'few seconds' . It stop only for an instant as its movement changes from upwards to downwards.
An arrow is shot straight up at an initial velocity of 200 meters per seconds. How long will it be before beginning to fall?
40.81632653 or (rounded to the nearest 10th) 40.8 seconds
A skydiver steps from a helicopter and falls for 5 seconds before reaching her terminal velocity during this 5 second interval her acceleration?
the crate will reach terminal velocity last, but hit the ground frist.

increase- your speed will increase until terminal velocity is reached. From there it will stay constant.

What is the skydiver's downward velocity at that instant just before starting to fall?
The same as that of the aircraft that he /she is in. If flying level, it would be zero.

If you are 5 kilometers from the place where lightning strikes a tree how long does it take before you see the lightning?
.0000166782047599 seconds, or nearly instantaneously.
What is the momentum of a 500 kg truck before it strikes a 300 kg parked car?
Momentum defined as p=mv.. The momentum of the truck depends on its velocity

When was Before the Lightning Strikes created?
Before the Lightning Strikes was created on 1959-10-04.

In physics is there a negative time?
Absolutely! If an object has been already traveling for 30 seconds. If you start your watch at 30 seconds, then t = 0 at 30 seconds! The velocity of the object 3 seconds BEFORE you start the watch would then be t = -3 and 3 seconds after you start the watch would be t = 3.
