## Homework Statement

A top fuel dragster accelerates at six times the acceleration of gravity. Its mass is 3000kg and it has an initial frictional force of 6000N

M = 3000kg

A = 60ms

^{-2}(Lets just say gravity = 10ms

^{-2}down)

## Homework Equations

a) What is the total force?

b) What is the engine force?

c) At 300km/h the frictional force has increased to 50,000N, what is its acceleration at this speed?

## The Attempt at a Solution

a) F

_{net}= MA

= 60*3000

= 180,000N or 180kN

b) Sorry I have no idea what this is asking for

c) Sorry I have no idea what this is asking for

Basically I don't understand what to do in those questions. If anyone could point me in the right direction it'd be greatly appreciated
