I've tried the same formula I used when I started this topic on another assignment of the same type. It shows that the solution in the assignment was wrong!
IDIOTS! We were right al along :D Thanks for your help guys!
I calculated the velocity when the box has slided down the plane:
v= 5,581963937m/s (The speed is just before the box hit's the spring
Then I put in the velocity in the ecuation I wrote earlier, together with the spring constant and then I solved for x
There is no pic. for the problem, but I get your point. Does it really make that big differernce? And We have never had such problems before, so i think the spring is aligned with the plane
I've tried a few times on this problem but I can't get the right answer...
A box with mass m=1,05 kg slides down a ramp with angle=42.39°. Kinetic friction μ=0,1646 between the ramp and the box. It starts from rest. g=9,806m/s². The box hit's a spring with: k=792 N/m after sliding the...
adx = adv
Where x is the distance "s"
so I get this:
(1/2)*(x^2) = v2^2 - V1^2
Where v2 is the final speed and v1 is the starting speed=0..
Am i right or wrong?
Homework Statement
A car accelerates with the acceleration a(s)=k*s^n m/s^2
s= distance in m
k = 5,8
n=0,7351
The car starts the acceleration from 0 m/s
How far has the car traveled when it reaches the speed 4,61m/s?
