While you are going 60 mph, it will take approximately 180 feet to stop, A is the correct choice. I know some of the question is missing, so I researched it and found the correct answer.
Answer:
117.72kW
Explanation:
Given data
Mass m= 50kg
height x = 2m
time taken = 2 minutes= 129 seconds
let us find the work done
WD= force * distance
WD= mgx
WD= 50*9.81*2
WD= 981 Joules
Let us find the power
Power= work * time
Power= 981*120
Power= 117720
Power= 117.72 kW
Hence the power spent is 117.72kW
B. Average kinetic Energy
Temperature refers to the average kinetic energy of the particles of a substance, ie. the more they move/vibrate in place, the hotter the substance is.
