Two dogs fight over a bone. The larger of the two pulls on the bone to the right with a force of 42 N. The smaller one pulls to the left with a force of 35 N a. Draw the free-body diagram for thebone.
b. What is the net force acting on thebone?
c. If the bone has a mass of 2.5 kg, whatis its acceleration?

Explanation:

A

35 N  Small Dog <BONE> Bigger Dog 42 N

B

Fnet = Large Dog - small dog The forces are subtracted because they are acting in opposite Directions.

Fnet = 42 - 35

Fnet = 7 N

C

m = 2.5 kg

F = 7 N

a = ?

F = m * a

7 = 2.5 a

a = 7 / 2.5

a = 2.8 m/s^2
