Physics velocity mass??

Question

how to get the mass of object given in inclined plain initial velocity and final and the height. diagram looks like a phytagorean.??

Answer 1

I am not sure that I "see" the set up to your problem...

If you are given the distance traveled on the plane and the initial and final velocities, you can get the acceleration from...

vf^2 = vo^2 + 2*a*distance

The net force produces this acceleration and...

Fnet = mass* accel.  

You would also need to be told the net force, since the motion is not a function of mass in these problems.
