Answer:
Vertical Height = 0.784 meter, Speed back at starting point = 10 m/s
Explanation:
Given Data:
V is the overall velocity vector, 
and 
are its initial vertical and horizontal components
To find:
Max Height 
achieved
Calculation:
1) Using the 
equation of motion, we know
2) In terms of gravity 
height and the vertical component of Velocity 
.
3) As 
as at maximum height the vertical component of velocity is zero maximum height achieved
putting values
4) 
5) As for the speed when it reaches back its starting point, it will have a speed similar to its launching speed, the reason being the absence of air friction (Air drag)
Answer:
The neutron can be found in the nucleus of the atom with the proton.
Assume that energy losses (due to aerodynamic resistance or bearing friction are negligible).
At the highest point, the pendulum has its maximum potential energy (PE) and zero kinetic energy (KE). The total energy is equal to the PE = 141 J.
At the lowest point, the pendulum has its maximum KE, and zero PE. The total energy is equal to the KE.
Because energy is preserved, therefore
KE at the lowest point = PE at the highest point = 141 J.
Answer: 141 J
