Question

Two students run a race. Student A is 50 kg and runs at 5 m/s. Student B is 30 kg and runs at 2 m/s. Which

student has more Kinetic energy?

Answer 1

Step-by-step explanation:

KEA = ½(50)5² = 625 J

KEB = ½(30)2² = 60 J

Student A has more kinetic energy.

More than ten times more kinetic energy due to both larger mass and higher velocity.
