A group of sledding dogsis used to pull two sleds across the ice. The mass of the first sled behind the dogsis 48kg and the mass of the second sled is 36kg. There is anappliedforce of 272N [forward] on the sleds. The coefficient of kinetic friction for the sleds on ice is 0.15. Assume that no other frictional forces act on the dogs. a. Calculate the force of friction acting on both sleds.
b. Calculate the acceleration of the sleds.

Suppose you have a box. which of these is not necessarily a true statement regarding the relationship between the force applied to the box, the work done on the box, and the distance the box is moved? a. if the box is not moved, no force is being applied to the box. b. if no force is applied to the box, no work is done on the box. c. if work is done on the box, then a force is applied to the box. d. if work is done on the box, then the box is moved a distance.
