Question

Another child is on a swing next to the first. This child has a mass of 48 kg and a maximum kinetic energy of 3800 J. What is the velocity of this child? ​

Answer 1

Answer:12.583m/s

Step-by-step explanation:

`KE=(1)/(2)mv^(2)`

`3800=(1)/(2)(48)v^(2)`

`(3800)/(24)=v^(2)`

`√(158.33) = v\\12.583m/s=v`
