Answer:
v = 24.5 m
Explanation:
Average speed is defined as
v = ( - x₀) / t
The distance is
x = v t
In this case we can find the speed
v = (v_nort ¾ t + v_sud ¼ t) / t
v = 45 ¾ - 37 ¼
v = 24.5 m
To solve this problem we will apply the concepts related to energy conservation. For this purpose we will have that all the changes occurred in the energy change will be equivalent to the change in the potential and kinematic energies of the body. At the same time we will consider that the change in the final energy of the system will be reflected in the work of the system, therefore,
Here,
F = Force
m = mass
v = Velocity
h = Height
d = Distance
Replacing we have,
Therefore the launch energy is 365061ft-lb
