Hey there!:
The potential energy is U = m*g*h
Substitute 560.0 J for U = m*g*h so, 560.0 = m*g*h
g = 9.8 m/s²
50 ft in meters :
1 ft = 0.3048 m
50 ft = 50 * 0.3048 => 15.24 m
m = 560.0 / g*h
m = 560.0 / 9.8 * 15.24
m = 560.0 / 149.352
m = 3.74 kg
35 ft in m : 35 * 0.3048 => 10.668 m
The change initial in potencial energy from point A to B is:
mg ( h1 - h2 ) = 3.74* ( 9.8 )* (15.24 - 10.668 )
=> 36.652 * ( 15.24 - 10.688 ) =
36.652 * 4.552 => 167.57 J
According to the conservation of energy
The change in potencial energy should be equal to the change in kinetic energy , so the , the change in kinetic energy is :
ΔK = 167.57 J
Hope that helps!
