Having trouble on the question below. Would you do need to convert the km to meters and then multiply (4700*9.8*165500)?
The first woman in space, cosmonaut Valentina Tereshkova, flew in 1963. She orbited the earth 48 times during her 70 hour 50 minute flight at an average altitude of 165.5 km above the surface of the earth. Her spacecraft, Vostok 6, had a mass of about 4700 kg. What was her average gravitational potential energy? Thanks...
