Question

Determine the kinetic energy of a 48-kg roller coaster car moving with a speed of 5 m/s using the formula KE = 0.5 * M * V².

A) 1600 Joules
B) 600 Joules
C) 60 Joules
D) 6000 Joules

Answer 1

The kinetic energy of a 48-kg roller coaster car moving at a speed of 5 m/s is calculated using the formula KE = 0.5 * M * V², which gives us 600 Joules, making option B the correct answer.

Step-by-step explanation:

To determine the kinetic energy of a 48-kg roller coaster car moving with a speed of 5 m/s, you can use the formula KE = 0.5 * M * V². Plugging in the values provided:

KE = 0.5 * 48 kg * (5 m/s)²

KE = 0.5 * 48 * 25

KE = 0.5 * 1200

KE = 600 Joules

Therefore, the correct answer is B) 600 Joules.
