Question

A 0.25-g paint chip comes off a satellite

orbiting Earth. The velocity of the paint
chip is 7000 m/s. Which is the kinetic
energy of the paint chip?

Answer 1

6125 J

Step-by-step explanation:

Kinetic energy,
`KE=0.5mv^(2)` where m is the mass of the paint chip while v is the velocity of the paint chip. Substituting m with 0.25g= 0.00025 Kg while v is 7000 m/s then

`KE=0.5* 0.00025* 7000^(2)=6125 J`

Therefore, the kinetic energy is equivalent to 6125 J
