Question

Given speed of at of 83.33 m/s, what is the total friction+drag force on the car

Answer 1

i think alll you really need to do is think about the calculations

Answer 2

well its part 2 of a problem I got part 1. Just not sure how to find friction and drag force.

Answer 3

do you have a textbook?

Answer 4

yes

Answer 5

is there anything that would help you or maybe definitions?

Answer 6

im thinking i could calculate static friction, because its constant speed

Answer 7

good

Answer 8

and you probably can figure it out

Answer 9

do you go to connections academy?

Answer 10

haha no

Answer 11

what is the haha for?

Answer 12

hmm i dont have coefficient of static friction

Answer 13

cause i have no idea what that is

Answer 14

its a onlne school.

Answer 15

ahh, i got to a community college

Answer 16

i am in 9th grade.

Answer 17

lol, why did u reply to my question

Answer 18

cause i know it

Answer 19

are most people on here college students?

Answer 20

If I may make an observation, I don't think you have enough information to find the friction+drag forces.

Answer 21

hmm, what information would we need here?

Answer 22

You only have the speed given which tells nothing about what forces are acting on the car. If you had the time it took it to come to rest that is putting the car in neutral and letting it coast to a stop could tell you the average forces acting that cause the car to stop.

Answer 23

I almost forgot. You also need the mass of the car

Answer 24

i have mass of teh car

Answer 25

What other info do you have?

Answer 26

well i had to figure out the angular velocuty of the wheel

Answer 27

given mass of car, and wheel size

Answer 28

That's it?

Answer 29

Got to go.
