Ah its actually been one of those days, how can i not expand properly? Thanks a lot for the help :)

But i seem to get: \sqrt{1-\frac{E^{2}}{E^{2}+M_{0}^{2}c^{2}}} But now I am stuck thanks for all the help

Im not the best with latex but i can show you the equation i got on here if you can understand it So i got gamma = 1/(sqrt(1-((((E*c)/(E+m*c^2))^2)/c^2)))

I've tried this but it didnt seem to simplify and when i put it into the equation i found it made it even worse. Any ideas?

Homework Statement A photon collides with a stationary particle of rest mass m0 and is absorbed. Find the mass and velocity of the composite particle Homework Equations Conservation of energy: E + m0 * c^2 = \gamma * mt *c^2 where mt is the total mass Conservation...

Yeah sorry i meant μC and i used the horizontal distance given. I take it i should use conservation of energy to find the new distance when it reaches the given speed?

Question A point charge q_{1}=15\muF is held fixed in space. From a horizontal distance of 4.00cm , a small sphere with mass 4.00\times10^{-3}kg and charge q_{2}=2.00\muF is fired toward the fixed charge with an initial speed of 43.0m/s. Gravity can be neglected. What is the acceleration...
