Answer 1

Answer:

874800

Explanation:

1/2mv^2

M= 600kg

V= 54km/h

Solve it.

Answer 2

Final Answer:-

Kinetic energy is 67500 J

Explanation:-

Given-

• Mass of car = 600kg
• Speed of car = 54km/h = 15m/s

We need to find kinetic energy.

As we know that kinetic energy is equal to 1/2mv^2, where m and v are equals to mass and velocity of object.

KE = 1/2 mv²

KE = 1/2 × 600 × (15)^2

KE = 1/2 × 600 × 225

KE = 300 × 225

KE = 67500 J

Therefore, kinetic energy of car is 67500 J.
