A rocket of maxx `3xx10^6`kg takes off from a launching pad and acquires a verticle velcoity of 1km//s and an altitude of 25km. Calculate its (a) potential energy (b) kineitc energy.

A rocket of 3 xx10^6 kg mass takes off from a launching pad and acquires a vertical velocity of 1 km/s at an altitude of 25 km. Calculate the potential energy, and the kinetic energy.

A rocket of mass100 tonnesis propelled with a vertical velocity 1 km/s. Calculate kinetic energy

As you have learnt in the text, a geostationary satellite orbits the earth at a height of nearly 36,000 km from the surface of the earth. What is the potential due to earth’s gravity at the site of this satellite ? (Take the potential energy at infinity to be zero). Mass of the earth = 6.0 xx 10^(24) kg." radius" = 6400 km .
