How much longer is the train than the tunnel

Reference no: EM13504671

A supertrain of proper length 200 m travels at a speed of 0.9 times the speed of light (relative to the tunnel) as it passes through a tunnel having proper length 80 m. In the reference frame of the tunnel, how much longer is the train than the tunnel? (A positive answer means the train is longer than the tunnel and a negative answer means the tunnel is longer than the train.)
