The potential energy as it reaches a height of 0.63 meters is mgh
Since total mechanical energy is conserved, Set that equal to the initial kinetic energy which is 0.5mv^2
2*9.8*0.63 = 0.5*2*v^2
12.348 = v^2
3.51 = v
That's it's initial speed.
Answer:
2.2 m/s^2
Explanation:
Acceleration = Force / Mass
= 7.92 / 3.6 = 2.2m/s^2
Hope this help you :3
You realized that you are stupid....
Answer:
Force, 
Explanation:
Distance between proton is 0.005 m
It is required to find the force between two protons. Protons have of positive charge of
. Two protons will have a force of repulsion between them. The force is given by :

So, the force between two protons is
.
