A Savior In Physics Please Help In This Question!!!!!!!!!!!!!!!!

Answer 1

Hello there!

To find the speed when you have the kinetic energy and the mass, you just start with the kinetic energy formula then solve for speed.

Kinetic energy =
`(1)/(2) mv^2`

V =
`\sqrt{ \frac{2*K.E{} }m`


`V = \sqrt{ (2*1.09*10 ^(-3) )/(9.34*10 ^(-2) ) }`

V =
`(0.00218)/(0.0934)`

V = 0.02334

Thus, the speed is 0.02 m/s

I hope this helps!
