Problem # 2: A motorcycle with a mass of 40-kg travels at a constant speed of 30 m/s. What is the kinetic energy of the motorcycle?​

Sagot :

[tex]\tt{\huge{\blue{Explanation:}}}[/tex]

The kinetic energy of a moving object is given by

[tex]\boxed{KE = \frac{1}{2}mv^{2}}[/tex]

where:

KE = kinetic energy

m = mass

v = speed

[tex]\tt{\huge{\red{Solution:}}}[/tex]

Solving for KE

[tex]KE = \dfrac{1}{2}mv^{2}[/tex]

[tex]KE = \dfrac{1}{2}(\text{40 kg})(\text{30 m/s})^{2}[/tex]

[tex]\boxed{KE = \text{18,000 J}}[/tex]

Therefore, the kinetic energy of the motorcycle is 18,000 J.
