Explanation:
Answer: time is the same
Explanation: the distance(H) is the same in each case .
we drop the balls , no drag force using basic kimnematics
y =gt*t/2 , yo=0 , vo=0 , y=H , so : t= sqrt(2H/g)
comment: if distance H starts to grow....we could begin to note a difference because of gravity g is smaller as we go up
Answer:
<h2>245 J</h2>
Explanation:
The kinetic energy of an object can be found by using the formula
m is the mass
v is the velocity
From the question we have
We have the final answer as
<h3>245 J</h3>
Hope this helps you
