#### Question

# Physics homework help needed...?

The motion of a very massive object is hardly affected by what would seem to be a substantial force. Consider a supertanker, with a mass of 2.8×10^8 kg. If it is pushed by a rocket motor (thrust force of a rocket motor is 5x10^6 N) and is subject to no other forces, what will be the magnitude of its acceleration? (all info given is provided)...thanks in advance

#### Answer

This problem is extremely easy. First, look at what you need to find: acceleration. What else are you given? Mass and force? Can you think of any equation that will help you with this problem? Try Newton's second law of motion:

F = ma

Rearrange the equation to solve for a:

a = F/m

It should be EXTREMELY easy to solve now.
