When you stir coffee in a cup and stop, the swirling motion continues due to inertia. 2. When pedaling a bicycle and you stop pedaling, the bike continues going until friction or gravity slows it down. 3. If the wind is blowing, tree branches are moving. Fruits that fall from the tree will fall in the direction the wind is moving into because of inertia. 4. When pulling a Band-Aid off, it is better to pull it fast. Your skin will remain at rest due to inertia, and the force pulls the Band-Aid off. 5. If a car is moving forward it will continue to move forward unless friction or the brakes interfere with its movement. A. inertia of rest B. inertia of motion C. inertia of direction

Problem 2 Cart and Pulley Apparatus Newton’s 2nd Law may be applied to a simple system consisting of a frictionless horizontal track on which a cart plus some masses on it (total mass M), that is connected by a massless string over a frictionless pulley to a mass, m, (hanger plus some mass attached) In lab, in Activity 1, you will use a cart and track apparatus, like in the figure at right, and a hanging mass (hanger plus mass) that pulls the cart.You are to derive an equation for the acceleration of the cart. In lab, you will use this equipment setup to experimentally verify your answer. In the following steps, use the following notation: M = total mass of cart (including contents) m = mass of weight hanger T = tension force in the string a = acceleration Applying Newton's 2nd Law to the Cart – Pulley Apparatus 1.

An adventurous archaeologist crosses between two rock cliffs by slowly going hand-over-hand along a rope stretched between the cliffs. He stops to rest at the middle of the rope (Figure 1). The rope will break if the tension in it exceeds 2.55×104 NN , and our hero's mass is 87.6 kgkg1. If the angle between the rope and the horizontal is θθtheta = 11.1 ∘∘, find the tension in the rope?2. What is the smallest value the angle θθ can have if the rope is not to break?
