Question

What is the kinetic energy of Mickey Mouse, who weighs 3 kg and is running with a velocity of 7 m/s?

A) 14 J
B) 73.50 J
C) 0.33 J
D) 2.33 J

Answer 1

The kinetic energy of Mickey Mouse, who weighs 3 kg and is running with a velocity of 7 m/s, is 73.5 joules.

Step-by-step explanation:

The kinetic energy (KE) of an object can be calculated using the formula KE = 0.5 × mass × velocity2. For Mickey Mouse, who weighs 3 kg and is running with a velocity of 7 m/s, the kinetic energy can be calculated as follows:

KE = 0.5 × 3 kg × (7 m/s)2

KE = 0.5 × 3 kg × 49 m2/s2

KE = 0.5 × 3 kg × 49 J

KE = 1.5 kg × 49 J

KE = 73.5 J

Therefore, the kinetic energy of Mickey Mouse is 73.5 joules.
