Answer:
0.37 m
Explanation:
Given :
Window height, 
= 1.27 m
The flowerpot falls 0.84 m off the window height, i.e.
= (1.27 x 0.84 ) m in a time span of 
seconds.
Assuming that the speed of the pot just above the window is v then,
![$v=\left(\frac{30}{8}\right) \left[ (1.27 \times 0.84) - \left( \frac{1}{2} \times 9.81 \times \left( \frac{8}{30 \right)^2 \right) \right]}$](https://tex.z-dn.net/?f=%24v%3D%5Cleft%28%5Cfrac%7B30%7D%7B8%7D%5Cright%29%20%5Cleft%5B%20%281.27%20%5Ctimes%200.84%29%20-%20%5Cleft%28%20%5Cfrac%7B1%7D%7B2%7D%20%5Ctimes%209.81%20%5Ctimes%20%5Cleft%28%20%5Cfrac%7B8%7D%7B30%20%5Cright%29%5E2%20%5Cright%29%20%5Cright%5D%7D%24)
m/s
Initially the pot was dropped from rest. So, u = 0.
If it has fallen from a height of h above the window then,
h = 0.37 m
Gravity is the name of the force that keeps the planets in orbit
89.67J
Explanation:
Given parameters:
Mass of rock = 6.1kg
Height of fall = 1.5m
Unknown:
Potential energy = ?
Solution:
The potential energy is the energy at rest or due to the position of a body.
Potential energy is mathematically expressed as;
Potential energy = mgh
m is the mass of the rock
g is the acceleration due to gravity of the rock
h is the height of the rock
Potential energy = 6.1 x 9.8 x 1.5 = 89.67J
