Answer:
If width = 60 m, length = 195 m.
If width = 150 m, length = 465 m.
Step-by-step explanation:
The area of a rectangle is l * w or length times width.
So we can set an equation (letting w = width and x = length)
w =
Part 1: width = 60m:
60 =
65 =
x = 195 m
Part 2: width = 150 m:
150 =
155 =
x = 465 m
Answer:
Factor by which kinetic energy increase = 4 times
Step-by-step explanation:
Given,
= 15.64 m/s
Initial kinetic energy of the car is given by,
= 183606.46 J
= 31.29 m/s
So, final kinetic energy of car is given by
= 734425.84 J
Now, the ratio of final to initial kinetic energy can be given by,
Hence, the kinetic energy will increase by 4 times.
