Answer:
The work done by the worker on the crate is 4830 J.
Explanation:
Given that,
Force = 1080 N
Horizontal force = 345 N
Distance d = 14 m
Coefficient of friction = 0.22
We need to calculate the work done
Using formula of work done
F = force
d = distance
Put the value into the formula
Hence, The work done by the worker on the crate is 4830 J.
Answer:
A ball moving through the air.
Explanation:
The ball has momentum which is a form of kinetic energy.
I don't know if that is correct, but I hope it helps!!!!
Kinetic energy=1/2mv^2
=1/2(142*10^-3)(42.9)^2=130.6=131J
Displacement is how much of a liquid (typically water for simplicity in the metric system) is pushed aside when another object is completely submerged. For example, when a 100mL of water has a block placed into it, and rises to 150mL, the block has displaced the water.
