Explanation:
define speed because change in motion is known as it is also the definition of speed and if there is change in motion then there will be increase of speed or decrease of speed so the answer is speed
Answer:
7m
Explanation:
5+2=7 and then I added in the "m" and got 7m, so presumably g=7m.
The work done by the force in pulling the block all the way to the top of the ramp is 3.486 kJ.
<h3>What is work done?</h3>
Work done is equal to product of force applied and distance moved.
Work = Force x Distance
Given is a block with a weight of 620 N is pulled up at a constant speed on a very smooth ramp by a constant force. The angle of the ramp with respect to the horizontal is θ = 23.5° and the length of the ramp is l = 14.1 m.
From the Newton's law of motion,
ma =F-mg sinθ =0
So, the force F = mg sinθ
Plug the values, we get
F = 620N x sin 23.5°
F = 247.224 N
Work done by motor is W= F x d
The force is equal to the weight F = mg
So, W = 247.224 x 14.1
W = 3.486 kJ
Thus, the work done by the force in pulling the block all the way to the top of the ramp is 3.486 kJ.

The item with the most inertia is the one with the greatest mass.
It's easy to identify because it's also the heaviest one.
There are a great many other issues that make something
difficult for movers to move, besides its weight. Size, shape,
handles, wheels, getting it around tight corners, etc. So we
can't necessarily say that the heaviest item is the one that
presents the biggest problem for the movers.
