1. A rocket was found to be 150m when measured on earth.It then leaves and move at a constant velocity of 2 x 10m/s. What is its new length?

2. Two spaceships A and B are moving in opposite directions, A with a speed of 0.9c while B with a speed of 6c. Find the relative velocity of B with respect to A.

3.Show that the force acting on a particle as observed by two observers in the inertial frames if reference is the same is the same. Given v<<c
