Question

If you drive your 1,000 kg car from sea level up to the mountain, which is 366 m above sea level, how much will you have increased your car's potential energy?(consider : g=10m/s2) *

1 point

a) 366,000 J

b) 3,660,000 J

c) 2.73 J

d) 20.73 J​

Answer 1

Option B. 3660000 J

Step-by-step explanation:

At the sea level, we'll assume that the height is 0 m. Hence, the potential energy at the sea level is zero.

Next, we shall determine the potential energy at a height of 366 m above the sea level. This can be obtained as follow:

Mass (m) = 1000 kg

Acceleration due to gravity (g) = 10 m/s²

Height (h) = 366 m

Potential energy (PE) =?

PE = mgh

PE = 1000 × 10 × 366

PE = 3660000 J

From the calculations made above, we can see clearly that the potential energy of the car at a height of 366 m above sea level is 3660000 J.

Hence, the potential energy of the car increases from 0 at the sea level to 3660000 J at 366 m above the sea level.
