Problem 87HP
A car of mass 1775 kg travels with a velocity of 100 km/h. Find the kinetic energy. Howhigh should the car be lifted in the standard gravitational field to have a potential energy that equals the kinetic energy?
ANSWER:
Solution 87 HP:
Step 1 of 2:-
Here we have to calculate the height where the potential energy will be equal to the kinetic energy.
The mass of the car is, m = 1775 kg.
The speed is, .
After converting the speed into m/s, it will be,
.
The kinetic energy of it will be,
(approximately)
