Calculating velocity in regards to the mass and kinetic energy of an object

[v3ra]

Homework Statement

How fast is a baseball with a mass of 145 g traveling if it has 94 J of kinetic energy?

Homework Equations

m = 145 g or 0.0145 kg
Ek = 94 J
v = ?

v = √2Ek/m

The Attempt at a Solution

I get...
v = √2(94)/0.0145 kg
v = √12966
v = 114

But my book says it should be 36 m/s. What am I doing wrong?

It also mentions that I need to recall that 1 J = 1 kg . m^2/s^2 but I am unsure how to incorporate this into the equation or if it is even necessary.

Your mass should be .145 kg.

Your mass should be 0.145 kg and not 0.0145kg
