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 =  $\frac{1}{2} mv^2$

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

$V = \sqrt{ \frac{2*1.09*10 ^{-3} }{9.34*10 ^{-2} } }$

V = $\frac{0.00218}{0.0934}$

V = 0.02334

Thus, the speed is 0.02 m/s

I hope this helps!
