I'm stuck on two problems 1 is #8(please see the pdf file):
I know I have to solve this equation with this:
F=MA
I calcualated F by taking the magnitude of Fx and Fy:
Fx=390*cos(9)i+335*cos(28)
Fy=390*sin(9)i+335*sin(28)
I got F as 687.756
and the mass is given: 3819kg
So I divided those and I got the answer as .180 but the comp. says it's wrong.
The second problem is 12(please see the pdf file):
I know I have to do this:
F = m*gm*a*cos(angle)
(is it right?)
(I calculated the acceleration and it is right)
so F = 3.35*9.83.35*5.67*cos(27)
and I got 26.06. What's wrong? with this?
Thanks in advance for the help.
