- What net force is required to make a 15 kg box move at a constant speed of 2.0 m/s.Suppose the glider and the hanger had equal masses mG = mh . In this situation, do you expect the magnitude of the acceleration of the glider will be: Select all that apply: Greater than g Equal to g Less than gWe often think of friction and air resistance as forces that we want to minimize because they can hinder the motion of an object. But they are not always undesirable, and in fact, can be an essential element in a machine or process. Identify one or two applications that depend on friction and air resistance. Explain how friction or air resistance works in those situations and what would happen if there were no friction or air resistance. Your initial post should be 75-150 words in length and is due on Sunday.
- For a short period of time, the frictional driving force acting on the wheels of the 2.3-Mg van is FD = (600+2) N, where t is in seconds. (Figure 1) Figure FD 1 of 1 Part A If the van has a speed of 22 km/h when t= 0, determine its speed when t = 5 s. Express your answer to three significant figures and include the appropriate units.

One of the forces is F1 = (1.88 N) + (-5.85 N). What is the other force? Number i + i j UnitsFollowing the collision with a tree, the car rapidly decelerates and comes to a full stop in 0.26 seconds. Given that the passenger in the car has a mass of 70.0 kg and experiences a restraining force from the seat belt amounting to 4038 N, what was the car's initial velocity just before the impact with the tree?
