1. Resultant force on a car

oh ok, thank you for all your help!
2. Resultant force on a car

Oh sorry for not making that clear: D and E are correlated, so the direction of the resultant force exerted by the car on the road.
3. Resultant force on a car

Ok, thank you so much. And for part e, I would then get the inverse tan of 10486/2793.9? 10486 being the force of gravity in the y direction and 2793.9 being the resultant force in the x direction.
4. Resultant force on a car

So would the forwards directing force be F=2150.7 (from answer a) and the backwards directed force coming from the trailer be T=643.2 (answer b), giving me a total resultant force of 2793.9. Sorry I'm still a confused.
5. Resultant force on a car

[SOLVED] Resultant force on a car Homework Statement A 1070 kg car is pulling a 320 kg trailer. Together the car and trailer move forward with an acceleration of 2.01 m/s2. Ignore any frictional force of air drag on the car and all frictional forces on the trailer. Determine the following. (a)...
6. Time and velocity

Ok, I'm still a little confused. So now I have set up one of my legs on my right triangle as 2 mi/hr for the direction of the water flow, and the other leg as 1.0 mile for the distance he covered. Then I solved for the resultant vector: square root of 2^2 + 1^2, which equals 2.24. Then I plugged...
7. Acceleration and velocity

oh, I get it! I'm supposed to break in down into it's x and y components. Thank you so much!
8. Acceleration and velocity

after the first 10 sec., its 250 meters away, then after the second 10 sec., its 750 meters
9. Time and velocity

Homework Statement A person who can swim at 2.0 mi/hr is swimming perpendicularly to the bank of a river (directly across the direction of river flow) which is flowing at 2.0 mi/hr. If the river is 1.0 mi wide, how long does it take to reach the other side? Homework Equations t=x/v...
10. Acceleration and velocity

[SOLVED] acceleration and velocity 1. Homework Statement EXACT PROBLEM: A car accelerates from rest W at 5.0m/s2 for 10.0s, then continues this acceleration NE for another 10.0s. What is the average velocity of the car for its journey to its position after 20.0s? 2. Homework Equations...
