I need to know how to find the mass of an object when given the force, initial velocity, and distance covered by the object. I’m guessing that I need to know acceleration but I don’t know how to figure that out.

Use the 3 equations below to work out 3 variables, namely a = acceleration and v = final velocity.

1. v = ut + 1/2at2

2. v2 – u2 = 2as

3. v = u + at

First use 1 and 2 to work out t and u (simultaneous equations)

Then use the other two equations to work out a.

Then F = ma

v = final velocity

u = initial velocity

t = time

s = distance

a = acceleration

F = force

m = mass

Hope this helps. If confused please IM
