*URGENT* Three sleds are attached to each other by a string and are being pulled over snow covered ground. The coefficient of kinetic friction between the sleds and snow is 0.20. They are being pulled with a force of 20. N. The first sled, m1, has a mass of 4.0 kg, the second sled, m2, has a mass of 1.0 kg, and the third sled, m3, has a mass of 1.0 kg. Find:
a) the force of friction on
(i) m1
(ii) m2
(iii) m3
(iv) The total amount of friction in the system
b) the acceleration of the sleds.
c) the tension in the string A (i. e. the tension in the string connecting sled m1 and sled m2).
d) Upload a Free-body diagram of each sled as well as the system.

Aperson gives a shopping cart an initial push along a horizontal floor to get it moving, and then lets go. the cart travels forward along the floor, gradually slowing as it moves. consider the horizontal force(s) on the cart while it is moving forward and slowing. which of the following statements is correct? (a) both a forward and a backward force are acting on the cart, but the forward force is larger. (b) only a forward force is acting which diminishes with time. (c) both a forward and a backward force are acting on the cart, but the backward force is larger. (d) only a backward force is acting, no forward force.
