15.)
6.6 * 10^-14 = 1/2 m (vf^2 -vi^2)
6.6 * 10^-14 * 2 / m = vf^2
vf = 3.8 * 10^8 m/s
16.)
Energy gained by the body as it accelerated from rest to 0.25 time of light speed,
E = 0.5*M*v^2
= 0.5*5.4*10^9*(0.25*3*10^8)^2
= 1.518*10^25 J
now let m is the mass that should be converted into energy.
Use Einsteins equation
E = m*c^2
==> m =E/c^2
= (1.518*10^25)/(3*10^8)^2
= 1.68*10^8 kg
