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)
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) Fnet = MA
= 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
