F=100 M=? A=65mph what does mass equal

The equation is F=MA so you need to isolate the variable M. You do this by dividing both sides by A.
So then you have F/A=M. Then you put 100 where F or force is and 65 where A is and your answer is 100/65. All you do now is simplify.
M=100/65
But you should look back and made sure you typed the problem correctly because I thought that 65 mph is velocity not acceleration.

I'm guessing you mean
F=100 N
a=65 MPH/s
First change the acceleration to m/s^2.
Since (roughly speaking)
1 m/s=2 MPH
then
65 MPH/s=32.5 m/s/s
Since F=ma, m=F/a
Just plug in and solve from there.

As you wrote it 65 mph is a velocity not acceleration so knowing force and velocity you can't calculate mass.

use formula F=ma
100=m(65)
m=100/65

I'm not helping you with homework, but I'll give you a hint.
Gravity accelerates at 9.8 centemeters per second.
