Answer:

D

Step-by-step explanation:

Kinetic energy is given by the formula  [tex]KE=\frac{1}{2}mv^2[/tex]

Where

KE is the kinetic energy (in joules)

m is the mass (in kg)

v is the velocity/rate ( in meters /second)

Given in the question, the mass is 63 kgs (m=63), velocity/rate is 10.6 meters per second (v=10.6). We plug them into the formula and calculate the KE:

[tex]KE=\frac{1}{2}mv^2\\KE=\frac{1}{2}(63)(10.6)^2\\KE=3539.34[/tex]

rounding to nearest tenth: KE = 3539.3 joules

Answer:

The correct answer option is D) 3539.3 joules

Step-by-step explanation:

We are given that a weighing 63 kilogram is sprinting at a rate of 10.6 meters per second and we are to find his kinetic energy.

Kinetic Energy = [tex] \frac { 1 } { 2 } m v ^ 2 [/tex]

Substituting the given values in the above formula to get:

Kinetic Energy = [tex] \frac { 1 } { 2 } \times 63 \times 10.6 ^ 2 [/tex]

Kinetic energy = 3539.3 joules
