A baseball traveling at 30 m/s [f] hits a catcher's mitt and comes to a stop in a distance of 5.0 cm. What is the acceleration?
Homework Equations
The Attempt at a Solution
Vi = 30 m/s
d = 0.05 m
a = ?
Vf = 0
Vf^2 = Vi^2 + 2a.d
0 = 90 m^2/s^2 + 2a.0.05m
- 90 m^2/s^2 =...

I would appreciate if you could tell me whether I'm correct or not. Thanks
Homework Statement
I need to find the relation between mass and acceleration.I was given the values above in a table, save for acceleration.
The mass of the object was given as well, so that I could plot acceleration v. mass
This is part of my chart.
