10. A 40 Kg crate (rubber chickens, perhaps?) is pulled across the ice with a rope. A force of 100 N is applied at an angle of 30 degrees with the horizontal to a rope attached to the crate, as shown above. Neglecting friction, calculate the acceleration of the crate. Calculate the upward force the ice exerts on the crate as it is pulled. (2.17m/s/s, 342N)​
