How Do You Calculate Relative Velocity Between Two Moving Cars?

AI Thread Summary
To calculate the relative velocity between two moving cars, first determine the components of each car's velocity. Car 1 travels north at 13 m/s, while Car 2's velocity must be broken down into its northward and westward components using trigonometric functions. After calculating these components, the relative velocity of Car 1 with respect to Car 2 can be found by subtracting Car 2's velocity from Car 1's. Similarly, the relative velocity of Car 2 with respect to Car 1 is calculated by reversing the subtraction. Understanding these calculations is essential to solving the problem accurately.

Homework Statement


if a car 1 is traveling north at 13m/s
and another car (2) is driving 20 degrees north of west at 7.0m/s

1.What is the velocity of car 1 relative to car 2
2.What is the velocity of car 2 relative to car 1?

i don't understand how to solve this? could someone help, are the relative velocities different?

Homework Equations


The Attempt at a Solution



My attempt...

components of car 2
sin 20 = op/hyp = op/7
y=2.39 North

cos20=x/7
x=6.58 West

then i don't know what to do

Of course we can help you solve the question, but we won't do it for you. You need to show some effort in solving the question yourself before we can help you.
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
