Can someone tell me how to do this question:
1. a) A car is traveling at 34.5 mi/h on a horizontal highway. The acceleration of gravity is 9.8 m/s^2. If the coefficient of static friction between road and tires on a rainy day is 0.064, what is the minimum distance in which the car will stop?
b)...
I got the velocity like this:
v-v0 = at = (4.05) (3.8) = 15.39 m/s. which was correct.
I tried to figure out the magnitude of object's position like this:
v = change in x / change in t
15.39 = change in x / 3.8
change in x = 58.48 m. which was the wrong answer.
What am I doing wrong?
Force problems- help pls!
I need help with these problems:
1. A 3.9 kg object is subjected to two forces, F1= (2.8N)i + (-4N)j and F2= (3.7N)i + (-10.4N)j. The object is at rest at the origin at time t= 0.
a) What is the magnitude of the object's acceleration? Got That one.
b) What is the...
I have no idea what to do in the 1st question because nothing is given except the distance. Can u just tell me what formulas to use? Just a little hint would be helpful.
