Answer:
Work done by the frictional force is 
Explanation:
It is given that,
Mass of the car, m = 1000 kg
Initial velocity of car, u = 26.1 m/s
Finally, it comes to rest, v = 0
We have to find the work done by the frictional forces. Work done is equal to the change in kinetic energy as per work - energy theorem i.e.
W = −340605 J
or
Hence, the correct option is (a).
The nall rolled 20 cm in 5 seconds
The internal combustion engine has been criticized for ages for its negative effects on human health as well as the deterioration that it has caused to the environment with the release of Carbon Dioxide (CO2). However, to settle the skeptics, studies have been conducted to prove the environmental benefits of the internal combustion engine.
According to an article written by Dr. Dwight R. Lee, an Economist at the University of Georgia, livestock is responsible for 18% of the greenhouse gases that cause global warming, a far higher statistic than the contribution made by automobiles and aircrafts. The internal combustion engine began replacing horses as a source of power in the early 1900s, which started replacing the outputs from animals with exhaust from tailpipes.
the correct answer is if you tripled the sphere volume, do the mat idiot
Answer: 0.28 m/s
Let
M1 = mass of Steve
V1 = velocity of Steve
M2 = mass of can
V2 = velocity of can
Because momentum is a conserved quantity:
P1 - P2 = 0
So
M1*V1 - M2*V2 = 0
78.0kg(V1) - 2.5kg(8.7m/s) = 0
78.0(V1) = 21.75
V1= 0.28 m/s
