Question

PLZ HELP!!! According to the classical form of Newton's second law, Ft=p, it would require force of 9.5 N acting for a year to accelerate a 1kg mass to a speed of .9999c. Using the relativistic form of Newton's second law, what force is required?

Answer 1

u could use\[F=\frac{ ma }{ (1-\frac{ v ^{2} }{ c ^{2} } )^{3/2}}\]

Answer 2

kk thx.
