A box of mass 18.3 kg with an initial velocity of 1.88 m/s slides down a plane, inclined at 28◦ with respect to the horizontal. The coefficient of kinetic friction is 0.77. The box stops after sliding a distance x. How far does the box slide? The acceleration due to gravity is 9.8 m/s 2 . The positive x-direction is down the plane. Answer in units of m.

Part B: What is the the work done by friction? Answer in units of J.

Part C: What is the work done by the normal force? Answer in units of J.

Part D: What is the magnitude of the work done by gravity? Answer in units of J.

Part E: What is the magnitude of the instantaneous power generated by friction half way between the initial and final positions? Answer in units of W.

Part F: What is the magnitude of the average power generated by friction from start to stop? Answer in units of W.

The kinds of birth control that work the best to prevent pregnancy are the implant and IUDs — they're also the most convenient to use, and the most foolproof. Other birth control methods, like the pill, ring, patch, and shot, are also really good at preventing pregnancy if you use them perfectly.

Paragard is over 99% effective—more effective than any other hormone-free birth control method*—and most hormonal methods. In fact, the American College of Obstetricians and Gynecologists (ACOG) recommends Paragard as one of the most reliable ways of preventing pregnancy.
