Thanks. I also was confused how the displacement would be less than 5km. Appreciate it for clarifying! How would you do this one then? 10km [N25E] + 5km [E]?

Homework Statement 10.0km [N] + 5.0km [E15S] Homework Equations Cosine Law The Attempt at a Solution If you draw it out you see that 10km is 90 degrees north. From the 10km end, you do E15S for 5km. Therefore, a = 10km, b = 5km, c = ?, C = 90 - 15 = 75. Therefore: c^2...

Homework Statement So I have this lab I have to do about finding the relationship between static friction and normal force. So basically I need to find find how the Static Friction and Normal Force relate by doing a lab experiment. The materials I have are: Spring balance / scale Weights...

How is the truck equation wrong? Please expand

1. The problem statement At the instant when the traffic light turns green, a car starts with a constant acceleration of 1.8 m/s^2 [forward]. At the same instant a truck traveling with a constant velocity of 8.5 m/s [forward] overtakes and passes the car. How far from the starting point will...

Lets say I had these two graphs: How would I find distance traveled, displacement, speed and velocity from these graphs? I would appreciate it if you could show your work. Thanks in advance.

Most of it. So let's say I had these two graphs: How would I find distance traveled, displacement, speed and velocity from these graphs? I would appreciate it if you could show your work. Thanks in advance.

I just want to know what is the difference on how to find Average velocity and Average speed when I try to find it in Velocity-Time graphs Also how do you find distance traveled and displacement in these velocity-time graphs. Thanks in advance for your help. Please use fairly simple...
