Answer:
64 J
Explanation:
W = ΔPE
W = mgΔh
W = (130 kg) (9.8 m/s²) (0.050 m)
W = 64 J
Answer:
a person pushes water with his hands in the backward direction is action and water in turns pushes him forward due to force is reaction.
Explanation:
f = ma
f = 500 × 2 = 1,000.
Answer: 1,000 N (Newtons)
Answer:
128.6 N
Explanation:
To find the force pulling the roller along the ground, we need to find the component of the force that is parallel to the ground. This can be done by using the equation:
where
F is the magnitude of the force
is the angle between the direction of the force and the direction of the ground level
Here we have:
F = 200 N
Substituting into the equation,
