3 problems 1. A 2.0 kg object is traveling at a constant speed of 1.4m/s[N] when it hits and ice patch. over the first 0.40m of the ice patch the object slows down to 0.85m/s[N]. what is coefficient of friction of the ice? (starting on a frictionless surface then slowing down) 2. an object starts from rest and then travels 6.0m in 4.0s. if the coefficient of friction is 0.10 and there was an applied force of 9.0N, what was the mass of the object? 3. Mr.Yahoo is pulling her friend's kids in a wagon with a force of 150N [E30*up] (which is equivalent to 130 N [E] and 75 N [up}. if the kids weigh 12kg, 8.0kg and the wagon weighs 3.0kg and the coefficient of friction is 0.43, what is their acceleration? Thank you in advance, please try to show full work and calculations and an idea of what a freebody diagram looks like.
