A projectile is launched with an initial velocity of v0 and an elevation angle of zero degrees. If the projectile were launched with the same initial velocity from the surface of Earth (g=9.80 m/s2) as from the surface of Mars (g=3.72 m/s2), which of the following would be true? a. Both the time of flight and the range would be larger on Mars. b. Both the time of flight and the range would be larger on Earth. c. The time of flight is greater on Earth but the range would be greater on Mars. d. The time of flight is greater on Mars but the range would be greater on Earth. e. The time of flight and the range would be the same on both planets

Relative Velocity

It is a measurement of an object with regards to the other object which is moving or stable or stationary. For example, if we are traveling in a bus and the bus is moving at speed of 50km/hr, then our speed is according to the nearby passenger on the bus is zero. According to them, we are not moving. But if one person standing on the ground or road observes us from outside of the bus, according to him we are moving at a speed of 50km/hr and the bus is also moving at a speed of 50km/hr. Now, the motion is recognized by the observer, it depends on a frame of reference or observer. This is motion called relative motion.
