A Jet airplane travelling at the speed of 500kmh^(-1) ejects its products of combustion at the speed of 1500kmh^(-1) relative to the jet plane.What is the speed of the latter with respect to an observer on the ground?

A jet airplane travelling at the speed of "500kmh^(-1)" jets its products of combustion at the speed of 1500kmh^(-1)relative to thejet plane what is the speed of the latter with respect to an observer on the ground

A boat moves right across a river with velocity 10Kmh^(-1) relative to water. The water has a uniform speed of 5.00Kmh^(-1) relative to the earth. Find the velocity of the boat' relative to an observer standing on either bank. If the width of river is 3.0Km , find the time it takes the baat to cross it.

A jet plane is flying horizontally with a velocity 600 km h^(-1) . The burnt gases are injecting from the rear of the get plane with the velocity 2000 km h^(-1) . With respect to the jet plane. Find the velocity of burnt gases with respect to a person on the ground.
