Question

Determine the kinetic energy of a 1500 kg roller coaster that is moving with a

speed of 35 m/s.
A) 200,000 J
B) 25,000
C) O 918,750
D) 920,000J

Answer 1

918,750 J

Step-by-step explanation:

The kinetic energy of an object can be found by using the formula

`k = (1)/(2) m {v}^(2) \\`

m is the mass in kg

v is the velocity in m/s

From the question

m = 1500 kg

v = 35 m/s

We have

`k = (1)/(2) * 1500 * {35}^(2) \\ = 750 * 1225 \\ = 918750`

We have the final answer as

918,750 J

Hope this helps you
