Read the scenario, then answer the questions. A 2 kg ball is thrown upward with a velocity of 15 m/s. What is the kinetic energy
HACTEHA [7]

Answer:

<h2>225 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

v is the velocity

From the question we have

k =  \frac{1}{2}  \times 2 \times  {15}^{2}  \\  = 1 \times 225 \\  = 225 \:  \:  \:  \:  \:  \:  \:  \:

We have the final answer as

<h3>225 J</h3>
