Answer:
What is velocity?
v = d/t = distance / time you need to know this formula !
= 10 m/ 4 s = 2.5 m/s
Explanation:
A fundamental force , is your answer .
<span>a resistance to change in motion</span>
Answer:
v_o= 12 m/s
Explanation:
The ball experienced a constant acceleration motion, so we need to apply the following formula:
Note: we set the acceleration of gravity as negative because it is going down.
the ball was thrown vertically upward with an initial velocity of 12 m/s
