Im not used to using that formula. I usually use force=mass X acceleration.

I've only taken physics for 2 months in my life, so please excuse me, but what the heck is W and what the heck is KE?

Homework Statement A supertanker of mass 1.0 X 10^8 travels 3.5km, reaching a speed of 4.1km/h from rest. What was the magnitude of the unbalanced force acting on it? 2. The attempt at a solution I got the acceleration(2.4m/s^2), but how do I fit this into the equation? The answer is...

I only have the time for the second part though. It doesn't tell me how long it travels for until after it stops.

A train travels 58km at an average velocity of 77km/h[E] waits for 5min, and then runs for half an hour at an average velocity of 64km/h[E]. Find the total displacement. HOW?!?? I am so confused. I have a test tomorrow and my teacher is useless. Please help me pass this course.

For the velocity time graph, how do I get the average speed for the entire set of data? It starts at the origin, then goes up to (120,25) for A, and then the final point is F which is (720, -140)

Sorry for not including it, but its a velocity time graph.

Homework Statement Im trying to get the displacement of a position on the graph with the following point 1: (600, -75) point 2: (720, -140) Now usually I use BxH/2, because it's a triangle, but I can't really get it for this. The answer shows 21 800. I've tried everything in my power...

Average Speed? How do I calculate?? How do I calculate average speed on a position time graph? Velocity time graph? Thanks Aaquib

Question 1. The Lotus Elise is capable of accelerating from 0 to 100km/h in 5 seconds. Graph HOW DO I GRAPH? WHAT DO I PUT ON MY X AND Y AXIS??
