Kyle is pushing a 100 kg crate of candy along the ice (coefficient of friction = 0 ) outside the Ice Fairy's castle. He applies a force of 100 N at an angle of 30 degrees (so he doesn't slip) relative to the horizontal.
He is expecting an acceleration of 1 m/s2, but is disappointed when he finds out the acceleration is less than that. He is worried the Ice Fairy will be angry if he is late.
Why is the acceleration less than Kyle is expecting based on the total force he is applying? Can you predict what the acceleration is?
