Question 2 (10 marks) a) Describe how you could determine the net force for an object using a free body diagram. b) For objects that are sliding across the ground (on Earth), how does the force of gravity influence the force of friction that they are experiencing? Question 3 (10 marks) a) If an object is placed on a ramp and starts to slide down towards the bottom of the ramp, what force(s) determine it's acceleration? b) Why would increasing the angle of a ramp increase the acceleration that an object that is sliding down the ramp experiences?
