Increasing a car's speed from 0 mph to 30 mph requires more work than that of 50 mph to 60 mph.
<h3>What is work?</h3>
Work is a measure of energy expended in moving an object. It is calculated by multiplying the force by the distance.
According to this question, work is required to move a car from one position to another.
The distance moved from 0 - 30mph is more than that moved from 50 - 60mph, therefore, increasing a car's speed from 0 mph to 30 mph requires more work than that of 50 mph to 60 mph.

The characteristics of high energy wave length are:
- High Frequencies
- Short wave length
And in term of color, it will be located on the red spectrum.
What diagram I can't find it.
Answer:
20.18 J
Explanation:
We are given that
Mass of bx=m=1.1 kg
Height=h=1.75 m
Initial speed of box=u=2.99 m/s
Final speed,v=2.56 m/s
We have to find the mechanical energy lost due to friction.
Energy at top=
J
Where 
At bottom,h'=0
Energy at bottom=
Energy lost=Energy(Top)-Energy(bottom)=23.78-3.6=20.18 J
