Answer:
KE = 100 J
Step-by-step explanation:
The question is asking you to use the formula with the values ...
m = 8 kg . . . . . this 'm' stands for mass
v = 5 m/s . . . . this 'm' stands for meters
Putting these values into the formula, we have ...
KE = 1/2(8 kg)(5 m/s)² = 100 kg·m²/s²
The units are equivalent to the derived SI unit "joules", abbreviated J.
The kinetic energy of the 8 kg mass is 100 J.
