Answer:
I really don't know but please if you find the correct answer tell me because I'm eager to know
Answer:
i think its false tell me if im wrong
Explanation:
Both cars are canceling out the energy of each other. The energy that is left over because one car has a bigger kinetic energy is the energy that is going to move BOTH the cars.
First Car : <em>0.5 * 2000kg * 3m/s^2 = 10.24 KJ</em>
Second Car :<em> 0.5 * 2000kg * 2m/s^2 = 4 KJ</em>
Leftover Energy : <em>10.24 KJ - 4 KJ = 6.24 KJ
</em>
Movement of BOTH cars :<em /><em>
6.24 = 4000kg * v^2
</em>v = √(6.24 / 4000) =0.04 m/s = 4 cm/s
Explanation:
The acceleration g varies by about 1/2 of 1 percent with position on Earth's surface, from about 9.78 metres per second per second at the Equator to approximately 9.83 metres per second per second at the poles.
Answer:A
Explanation:
Given
Skier A takes straight, smooth route while Skier B takes curvy, bumpy route to finish.
We know gravity is conservative in nature i.e. work done against it is independent of path followed
So work done by gravity for A and B is same
According to Work energy Theorem Change in the kinetic Energy is equal to work done by all the forces.
where h=vertical height of hill
thus 
which is same for both A and B
