A father pulls a sled and child with a force of 220 N by a rope making an angle of 20 degree with the horizontal. If the sled and child has a mass of 47 kg, to the nearest hundredth of 3 m s what is the acceleration of the sled and child? Two crates of mass 75 kg and 110 kg arc in contact and rest on a rough horizontal surface. A 620 N force is exerted on the...

A father pulls his child on a sled by pulling on a rope over his
shoulder as shown. Using the coefficient of friction for steel on
ice from table 1, calculate the acceleration of the sled if its
mass plus the child is 22 kg, assuming the sled is already in
motion.
