i really need some one to explain to me how to obtain the cofficant of friction in a cerntipidal force question: ex a car of some waight is turning at and the radious of the curve is somehitg there is an incline to the cruve wat is the min and max cofficant of firction? how would you do that i...

can u ppl please cheack if these answers are correct 1 a 1500 kg car travling at 25m/s {n} comes to a stop in 5 s wat is the net force ans- 7500 2. a boy aplies a horizantal forse of 45 n to a 10 kg trunk is the cofficient of friction between the boy and the floor is .35 detrimne...

the book answere was 35g

Newtons Laws? well i tied this prpblem you apply a force of .35 n [up] to a fork and it accelaraion is .15m/s^2 wats its mass in grams well i tried rearanging the force equation m=a/f but i got the worng answer si i thoght i rearanged wrong so i tried swithing the varables but that stil...

and how would u get time with the pythagrin therom?

the inverse would only get you the y or x componant

yeah but see umm u had to use the pathagriun therom to fin the hypatinous then use the sine law to find theda out of that and sry if i was sso late i had to eat diner

the angle i got was 33 i used the pathgrione therom then used the sine law to figer it out but now I am stuck

there are 10 questios in the review those are the only two i can't get

i drew the triangle but since this is vectores i don't know if i should add the negitive ot vf or just leav it likr that and i really don't know how to write the formulas on this so for me to do that would only take forever

well i got the first part but now I am stuck our teacher doesn't believe in giving formula sheets and as far as i got i don't have enogh info to get the time or displacment

sry but i waited for 3 hours and still no help

test tommorow need help please i have a test tommorw and i need answeres to the folowing questions if u can help i would be very thankful 1. a bout can travel at 1.85 m/s in still water at wat angle must it go in order to go stright across a 110 m river flowing at 1.20m/s b) if it goes...

thx for the explination

i was woundring if u could help me with the other thread please help me i really need it i have a test i need to pass
