Answer:

<h2>3000 J</h2>

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 = 60 kg

v = 10 m/s

We have

k =  \frac{1}{2}  \times 60 \times  {10}^{2}  \\  = 30 \times 100 \\  = 3000

We have the final answer as

<h3>3000 J</h3>

Hope this helps you

Answer:

\boxed {\boxed {\sf 3000 \ J}}

Explanation:

Kinetic energy is the energy an object has due to motion. It is calculated using the following formula:

KE=\frac{1}{2} mv^2

The mass of the go-cart is 60 kilograms and the velocity is 10 meters per second.

  • m= 60 kg
  • v= 10 m/s

Substitute the values into the formula.

KE= \frac{1}{2} (60 \ kg)(10 \ m/s)^2

Solve the exponent.

  • (10 m/s)² = 10 m/s * 10 m/s = 100 m²/s²

KE = \frac{ 1}{2} (60 \ kg)(100 \ m^2/s^2)

Multiply the numbers together.

KE= 30 \ kg * 100 \ m^2/s^2

KE= 3000 \ kg*m^2/s^2

Convert the units. 1 kilogram meter squared per second squared is equal to 1 Joule, so our answer of 3000 kg*m²/s² equals 3000 Joules.

KE= 3000 \ J

The go-cart has <u>3000 Joules</u> of kinetic energy.
