Question 17 (3 points) Jeb pulls a 250 g box of treats along the ground horizontally. If the coefficient of friction is 0.15, what is the acceleration of the box if he pulls with a force of 1.5 N? For your answers below enter 3 significant digits ONLY (no units or directions here; include them instead in full solutions). Ex: Actual answer: 12.035 You enter: 12.0 or Actual answer: 1234 You enter: 1230 Your full solutions should include an FBD. AQuestion 18 (4 points) Three sleds are tied together and pulled with a force of 150 N [E]. The mass of sled 1 is 13.0 kg, the mass of sled 2 is 10.0 kg, and the mass of sled 3 is 8.0 kg. Assume that the force of friction is negligible. What is the tension in rope A? rope A rope B sled 3 sled 2 sled 1 150 N (E)Question 19 {3' points) You need to drag a very heavy table {m = 5?ng across the kitchen floor, so you provide 54UN [R 35 U]. floor 8: desk create a frictional drag of 325M. a.
