The kinetic energy is 100,000 Joules, if a roller coaster of mass 2000 kg is rolling down a track with an instantaneous speed 10 m/s .

Explanation:

The given is,

Mass - 2000 kg

Instantaneous speed - 10 meter per second

Step: 1

Formula to calculate the kinetic energy,

$K.E = \frac{1}{2} mv^{2}$ ....................(1)

Where, K.E - Kinetic energy in joules

m - Mass in kg

v - Velocity or speed in meter per second

Step: 2

From the give,

m = 2000 kg

v = 10 m/s

Equation (1) becomes,

$K.E = \frac{1}{2} (2000)(10)^{2}$

= (0.5)(2000)(100)

= 100000

K.E = 100,000 Joules

Result:

The kinetic energy is 100,000 Joules, if a roller coaster of mass 2000 kg is rolling down a track with an instantaneous speed 10 m/s .
