Suppose you have a 120 kg wooden crate resting on a wood floor, with coefficient of static friction0.500 between these wood surfaces. (a) What maximum force can you exert horizontally on the cratewithout moving it? (b) If you continue to exert this force once the crate starts to slip, what will itsacceleration then be? The coefficient of sliding friction is known to be 0.300 for this situation.

You are playing with your daughter in the snow. She sits on a sled and asks you to slide her across a flat, horizontal field. You have a choice of (a) pushing her from behind, by applying a force downward on her shoulders at 30 below the horizontal (Fig. 5.2a) or (b) attaching a rope to the front of the sled and pulling with a force at 30 above the horizontal (Fig 5.2b). Which would be easier for you and why?
