Bryttani and Marco are fighting over a box of chocolates sitting on a table. Bryttani is pulling the box of chocolates to the right with a force of 8N. Marco is pulling the box to the left with a force of 7.5N. The box of chocolates has a mass of 0.2 kg and a coefficient of kinetic friction of 0.2
A. Calculate the friction on the box. Which direction is it?
B. Draw a free body diagram of the box of chocolates. Remember to include all forces exerted on the box.
C. Find the net force on the box in the horizontal (x) direction.
D. Find the acceleration of the box in the horizontal direction.
E. If the box started from rest (vox= 0), how far will it travel in 2 seconds? Which way?
