Is 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.
As a baseball is being caught, its speed goes from 30 to 0 m/s in about 0.005 its mass is 0.145.
A) What is the baseballs acceleration in m/s^2 and in g's?
B) What is the size of force acting on it?

Yes 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.
is a negative answer the answer is correct but the minus is missing.
