Question

A truck has a mass of 2,000 kg and is going 6 m/s. What is the kinetic energy of the truck? Solve using Kinetic Energy = (1/2) mass * velocity2
Group of answer
a) 12,000 J

b) 36,000 J

c) 72,000 J

d) 6,000 J

Answer 1

Answer:

b) 36,000 J

Explanation:

KE= 1/2 MV2

° 1/2 2000 × (6) 2

= 1/2 2000 × 36

= 1/2 72000

= 36000 J
