Question

A 6.8 KG object moves with a velocity of 8 M/S what’s it's kinetic energy?

Answer 1

Step-by-step explanation:

KE = ½mv² = ½(6.8)8² = 217.6 J

round as appropriate because that result is way too much precision for the inputs provided. Arguably should be 200 J based on the single significant digit of the velocity.
