Question

Shortly after the start of a dogsled race, you find yourself pulling your supplies across the snow (those $#@*&%^*& sled dogs are in BIG trouble). You apply a force of 300 N to a rope that is attached to the front box at an angle of 20 degrees above the horizontal. Mass of the front box M=40Kg, mass of the black box m=30kg, and there is no friction between the boxes and the snow.

A)Draw a free-body diagram of each box.

B)Show that the magnitude of the normal force on the front box is 289 N.

C)Show that the acceleration of the boxes 4.03 m/s² . Form the time you already have the boxes moving 2.0 m/s, determine the distance you move the boxes in 3.0 seconds.

D)Find the tension in the rope connecting the two boxes.
