with reference to the ship The speed of the rocket with reference
to earth is?

Ravi Gupta · Accepted Answer

Relative velocity of rocket with respect to the ship = velocity of ship-velocity of rocket
0 4 m/s =1 5×108-vv = 1 5×108-0
4 m/sthis is the velocity of the rocket with respect to the earth is also equal to v
