Question

Susan and Hannah are each riding a swing. Susan has a mass of 25 kilograms, and Hannah has a mass of 30 kilograms. Susan's swing moves with a velocity of 1 meters/second, while Hannah's swing moves with a velocity of 8.5 meters/second. Susan's kinetic energy is______joules.

Answer 1

Susan's kinetic energy can be calculated using the formula KE = 0.5 × mass × velocity squared, which results in 12.5 joules.

Step-by-step explanation:

The subject of the question is physics, specifically the concept of kinetic energy.

The formula for calculating kinetic energy (KE) is KE = 0.5 × mass × velocity2.

Susan has a mass of 25 kilograms and a velocity of 1 meter/second. Using the kinetic energy formula:

KE = 0.5 × 25 kg × (1 m/s)2 = 0.5 × 25 × 1 = 12.5 joules.

Therefore, Susan's kinetic energy is 12.5 joules.
