charge = current * time
q = 15 * 300 [5 min = 300 sec ]
q = 4500 C
Answer:
15.68 m/s
Explanation:
Given that,
She catches the ball 3.2 s later at the same height from which it was thrown.
When it reaches the maximum height, its height is equal to 0.
It will move under the action of gravity.
2 here comes for the time of ascent and descent.
So,
So, the initial upward speed of the ball is 15.68 m/s.
Answer:
Some examples of objects that are in free fall include:
A spacecraft in continuous orbit. The free fall would end once the propulsion devices turned on.
An stone dropped down an empty well.
An object, in projectile motion, on its descent.
