Problem 5: A box of mass m = 0.45 kg is set against a spring with a spring constant of k = 624 N/m which has been compressed by a distance of 0.1 m. Some distance in front of it, along a frictionless surface, is another spring with a spring constant of k2 = y 462 N/m. Part (a) How far, d, in meters, will the second spring compress when the box runs into it? Numeric A numeric value is expected and not an expression. d2 =, Part (b) How fast, v in meters per second, will the box be moving when it strikes the second spring? Numeric : A numeric value is expected and not an expression. 3.723 Part (c) Now assume that the surface is rough (that is, not frictionless). You perform the experiment and observe that the second spring only compresses a distance d,/2. How much energy, in joules, was lost to friction? Numeric A numeric value is expected and not an expression. Efric =

Newton’s Third Law of Motion

The horse pulls the cart and the cart pulls the horse in response as per Newton third law. So the big question is, “Don’t the two forces cancel each other? How does the cart accelerate?”
