Question

If a rolling ball had 18 joules of KE and is rolling 3 m/s, what is the mass?

Answer 1

F=MA FORSE= MASS X ACCELERATION

Step-by-step explanation:

So the answer should be 54 as 18 X 3 = 54

( I read the question wrong)

Answer 2

4Kg

Step-by-step explanation:

1/2mv²=K.E

1/2m×3²=18J

1/2m×9=18

9m=18×2

9m=36

m=36/9

m=4Kg
