Question

Calculate the relativistic speed of a particle at a time t- 6 s after it started from rest at 0 s . The mass of the particle is 6 x 10-2 kg and the force acting is l.1x 105

Answer 1

I can't really the given values.. so I'm going to assume something..
if you think that I assumed something wrong.. don't seethe calculations..
just focus on the method

F= m(v -u) /t

F=1.1 * 10 raised to the power of 5 N
t =6 sec
u = 0m/s
m = 6 * 10 raised to the power of -2 kg
substituting the values..

value of v = 1.09 * 10 raised to the power of 7 m/s

hope this helped
