C. The sun is 400 times farther from Earth than the moon is.
Answer:
t is time in s For example, a car accelerates in 5 s from 25 m/s to 3 5m/s. Its velocity changes by 35 - 25 = 10 m/s. Therefore its acceleration is 10 ÷ 5 = 2 m/s2
Explanation:
0.5mv^2
0.5 times 40 times 3^2
The kinetic energy is 180
