Acar is moving at 12 m/s and has a mass of 600 kg. what is the kinetic energy of the car? a)36,300 b)42,200 c)72,600 d)86,400

The kinetic energy of the car is, 43,200 kgm/s

Step-by-step explanation:

Using the formula:

          ....[1]

where,

K.E is the Kinetic Energy

m is the mass

and v is the velocity.

As per the statement:

a car is moving at 12 m/s and has a mass of 600 kg.

⇒m = 600kg and v = 12m/s

Substitute these given values in [1] we have;

⇒

⇒

Simplify:

⇒ kgm/s

Therefore, the kinetic energy of the car is, 43,200 kgm/s

answer: 80,000

step-by-step explanation:

the population doubles every day.

10,000*2=20,000 day 4

20,000*2=40,000 day 5

40,000*2=80,000 day 6
