- It's really question 2. I'll give you 10 minutes to answer it.
- (8 marks) The voyager space ship is currently beyond Pluto,
16.6 billion km from the sun, and travelling at 60,000 km per
hour. It is almost entirely unaffected by the Sun's gravity
or any other body's. How fast will it be going next year?
Paraphrase (or quote) Newton's principle that enables you to
determine this speed.
- (9 marks) The weight of Mars is roughly 6.4x(10^23)kg, and
its radius is 3400 km. How much force would it exert on someone
standing on its surface.
- (8 marks) Discuss the accuracy vs. calculation trade-off
regarding physical motion in videogames.
