Homework Statement
A large empty crate, with its lid in place, has a 9.50 kg mass hanging from a string attached to the center of the lid. If the crate were sitting (at rest) on a flat surface, the string would simply hang straight down such that the mass would not be touching the floor of the crate.
The crate is now pushed up a frictionless 10.0 degree slope with an acceleration of 2.25 m/s^2. During the push, what angle does the string make with the lid of the crate? Hint: you will need to solve two equations in two unknowns.
Homework Equations
f=ma
Newton's 2nd law
The Attempt at a Solution
I found the force required to push it up the ramp
f= 9.8(9.5)sin10 = 16.2N
Not sure if i even need that but i did it anyways.
so i really have no idea what 2 equations i need to get in order to solve the angle of the string?
can anyone help me on this please.
thank you
