1. Suppose you have a 120-kg wooden crate resting on a wood oor, with coefcient of static friction 0.500 between these wood surfaces. (a) What maximum force can you exert horizontally on the crate without moving it? (b) If you continue to exert this force once the crate starts to slip, what will its acceleration then be? The coefficient of sliding friction is known to be 0.300 for this situation. A team of eight dogs pulls a sled with waxed wood runners on wet snow (mush!) The dogs have average masses of 19.0 kg. and the loaded sled with Its rider has a mass of 210 kg. (a) Calcolate the acceleration of the dogs starting from rest if each dog exerts an average force of 185 N backward on the snow. (b) Calculate the force in the coupling between the dogs and the sled. A contestant in a winter sporting event pushes a 45.0-kg block of ice across a frozen lake as shown below. (a) Calculate the minimum force F he must exert to get the block moving. (b) What is its acceleration once it starts to move, if that force is maintained
