A) What is the baseballs acceleration in m/s^2 and in g's?

B) What is the size of force acting on it?

**drwls**, Tuesday, June 21, 2011 at 11:40amIs the 0.005 number supposed to be seconds? What about the mass,

In physics, numbers without units are useless. You MUST learn that.

A) acceleration = a = (speed change)/(time) = 6000 m/s^2

Divide that by 9.8 m/s^2 for the number of g's

B) Use F = m*a

m = 0.145 kg, I assume

The force will be in newtons.

**Ralph**, Tuesday, June 21, 2011 at 11:48amYes it is .005 s. And you assume right it is 0.145 kg. I am sorry of not putting in the units. I am really struggling with Physics.
