Weight equals mass times gravitational acceleration=400N, so mass=400/9.8=41kg approx.
Answer:
9727160J
Explanation:
Given parameters:
Height of elevator rise = 436m
Force exerted = 22310N
Unknown:
Work done by the elevator lifting mechanism = ?
Solution:
The work done by a body is the force applied to move a body in a specific direction;
Work done = force x distance moved
In this case, the force and distance moved is provided already;
Work done = 22310 x 436 = 9727160J
Explanation:
if we convert it into g/cm it'll be
2000 grams
Where the force is not perpendicular to the path of motion
are you missing the the situations ?
Answer:
You're right already. It's B)
