There are 3 round objects travelling east and there are 2 square objects traveling west. The objects traveling east have masses of 5 kg, 15, kg, and 2 kg. The objects traveling west have masses of 11 kg and 8 kg. What amount will the net force be in Newtons? Consider that all of the objects are accelerating at a rate of 1 m/s2.
net force = 3 N east
5 + 15 + 2 = 22
11 + 8 = 19
22 - 19 = 3

If two lizards each have a mass of 1.5 kg have climbed to the top of a tree. They run the risk of a strong breeze knocking them off the branch. If this were to occur, what amount of force would hit the ground based off of the amount of mass multiplied by the amount of acceleration? Consider that the rate of gravitational pull is known to be 9.8 m/s2 on Earth.
29.4 N would hit the ground
2 lizards x 1.5 kg x 9.8 m/s2
