What is the minimum speed required to leave the planet Earth (escape velocity)?(A) 20,000 km/h(B) 30,000 km/h(C) 40,000 km/h(D) 50,000 km/h

A body is projected from the earth's surface with the intention of letting it escape from the earth's gravitational field. What is the minimum escape velocity of the body? [Earth's radius = 6.4 x 103km, g = 10ms-2]

The escape velocity from the earth is 11.2km/sec. Another plant is having a mass 1000 times and radius 10 times that of the earth, then escape velocity at that planet will be

A space vehicle is traveling at 4500 km/h relative to the Earth when the exhausted rocket motor is disengaged and sent backward with a speed of 70 km/h relative to the command module. The mass of the motor is four times the mass of the module. What is the speed of the command module relative to Earth after the separation? km/h

Calculate the minimum time it takes to travel 1.5 km without breaking the speed limit.Use the Physics Equations Sheet.[4 marks]Minimum time = s
