Question

Read through the scenarios below and calculate the predicted change in kinetic energy of the object compared to a 100 kg ball traveling at 5 m/s.

A 1,000 kg ball traveling at 5 m/s would have ____ Kinetic energy
A 10 kg ball traveling at 5 m/s would have ____ kinetic energy
A 100 kg person falling at 5 m/s would have ____ Kinetic energy

Answer 1

10 times

tenth

the same

Explanation:

K.E is directly proportional to mass thus if the mass increases or decreses "k" times, then so does the K.E

Answer 2

1). 10 times more 2). 10 times less 3). the same

Explanation:
