Question

PLEASE HELP ME TIMED TEST!!!

A bowling ball has a kinetic energy of 14 J with a mass of 17 kg , how fast is the bowling ball moving? (round your answer to the nearest hundredths place)?

Answer 1

56

Step-by-step explanation:

I just want the points to be completely honest with you.

Answer 2

Step-by-step explanation:

`\boxed{\sf{K.E = (1)/(2) * m * v^2}}`

• Here, K . E or Kinetic Energy is given as 14 J
• Here, mass is 17 kg

Let's Do!

`\boxed{\sf{14 = (1)/(2) * 17 * v^2}}`

`\boxed{\sf{(14 * 2)/(17) = v^2}}`

`\boxed{\sf{ \sqrt{(14 * 2)/(17)}= v}}`

So, 1.283 m/s is the required answer.
