Answer: KE: 3.43 J
Explanation:
Kinetic energy is represented by the equation
m
, with 'm' representing mass and 'v' representing velocity. In this problem, the mass is 3.5 kg, and the velocity is 1.4m/s. Once you do the math, you get:
KE: 3.43 J
Note: J represents joules, the unit of measure used when writing the number for kinetic energy, as well as other things.
