Moe is carrying and supporting a large crate by exerting 1000 N. He is walking at constant velocity across a level, horizontal f
1 answer:
To solve this problem it is necessary to apply the agreements related to Strength and Work.
Work is defined as the amount of energy required to move a force over a certain distance.
Where,
F = Force
d = distance
Our values are given as,
F = 1000N
d = 10m
Therefore replacing,
W = 1000*10
W = 10000J
Therefore the neccesary work is 10000J or 10kJ.

Answer:
The hollow cylinder rolled up the inclined plane by 1.91 m
Explanation:
From the principle of conservation of mechanical energy, total kinetic energy = total potential energy
The total energy at the bottom of the inclined plane = total energy at the top of the inclined plane.
moment of inertia, I, of a hollow cylinder = ¹/₂mr²
substitute for I in the equation above;
given;
v₁ = 5.0 m/s
vf = 0
g = 9.8 m/s²
Therefore, the hollow cylinder rolled up the inclined plane by 1.91 m
