A 50-kg crate is pulled across the ice with a rope. A force of 80 N is applied at an angle of 36° with the horizontal. Neglecting friction, calculate

(a) the acceleration of the crate.

m/s2

(b) the upward force the ice exerts on the crate as it is pulled.

2. Relevant equations

F=Ma

law of Cosines

law of sines

3. The attempt at a solution

I have the upward force "Fay" which is 443N

using the law of sines 80sin36 = 443N which is the vertical force and usig the law of cosines the horizontal is 64.72N

I am not sure how to calculate the acceleration
