An egg of mass 5.8*10^-2 is dropped from a height of 1.5m onto a floor. Assuming air resistance is negligable, calculate for the egg:
a) loss of potential energy.
b) the kinetic enrgy just before impact.
c) the speed just before impact
d) the momentum just before impact.
So far i have done the potential energy one, and now I am stuck on the others. As the equation for KE is KE=1/2mV^2 but we do not know the velocity. And i cannot find out the velocity because we don't have the time either. So i was just wondering how i would work out b-d as all of their equations require velocity.
Thanks
