Question

What is the kinetic energy of a 9.0 kg steelhead if its speed is 16 m/s?
a. 1.4 x 102 J b. 1.8 J c. 1.2 x 103 J d. 2.3 x 103 J

Answer 1

We are given:

Mass of the Steelhead(m) = 9 kg

Velocity of the Steelhead(v) = 16 m/s

Calculating the Kinetic Energy:

KE = 1/2mv²

replacing the variables

KE = 1/2 * 9 * (16)²

KE = 1152 Joules
