A box is on top of a slope. The slope has NO FRICTION. V0 = 0 m/s, V = 4m/s.
MASS IS UNKNOWN
What is the height of the slope?
Equation for energy (i think)
The Attempt at a Solution
I attempted to find the accelleration, but I do not know what the accelleration is for an object running down a slope with no friction.
The only force applying to the box is gravity, I think.
I am new to Physics. I tried solving it, but to no avail.
I know this can be solved without knowing the mass, but I don't know how! Help?
