A rocket is fired vertically with a speed of 5 km `s^(-1)` from the earth’s surface. How far from the earth does the rocket go before returning to the earth ? Mass of the earth = `6.0 × 10^(24)` kg; mean radius of the earth = `6.4 × 10^6`m; G = `6.67 × 10^(–11)` N `m^2`
A rocket is fired from the earth towards the sun. At what distance from the earth’s centre is the gravitational force on the rocket zero ? Mass of the sun = `2×10^(30)` kg, mass of the earth = `6×10^(24)` kg. Neglect the effect of other planets etc. (orbital radius = `1.5 × 10^(11)`
A rocket is fired ‘vertically’ from the surface of mars with a speed of 2 km s–1. If 20% of its initial energy is lost due to martian atmospheric resistance, how far will the rocket go from the surface of mars before returning to it ? Mass of mars = `6.4×10^(23)` kg; radius of mars = 3395 km; G = G = `6.67 × 10^(–11)` N `m^2`
