Question

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

Answer 1

Answer:

918,750 J

Explanation:

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

$k = \frac{1}{2} m {v}^{2}$

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

$k = \frac{1}{2} \times 1500 \times {35}^{2} \\ = 750 \times 1225 \\ = 918750$

We have the final answer as

918,750 J

Hope this helps you
