Homework Statement In figure (a), a 5.4 kg dog stands on a 16 kg flatboat at distance D = 6.1 m from the shore. It walks 2.1 m along the boat toward shore and then stops. Assuming no friction between the boat and the water, find how far the dog is then from the shore. Homework...

thanks. i was thinking as the other force as pushing into the ground so it wouldn't be accelerating in that direction but then but 9.4sin(68)/3=2.905 and sqrt(2.905^2+1.8^2) = 3.4

Homework Statement Only two horizontal forces act on a 3.0 kg body that can move over a frictionless floor. One force is 9.0 N, acting due east, and the other is 9.4 N, acting 68° north of west. What is the magnitude of the body's acceleration? Homework Equations F=ma The Attempt at a...

Homework Statement The two blocks (m = 36 kg and M = 98 kg) in the figure below are not attached to each other. The coefficient of static friction between the blocks is µs = 0.48, but the surface beneath the larger block is frictionless. What is the minimum magnitude of the horizontal force...
