Aroller coaster has a "hump" and a "loop" for riders to enjoy (see picture). the top of the hump has a radius of curvature of 12 m and the loop has a radius of curvature of 15 m. (a) when going over the hump, the coaster is traveling with a speed of 9.0 m/s. a 100-kg rider is traveling on the coaster. what is the normal force of the rider’s seat on the rider when he is at the peak of the hump? compare this with the normal force he would experience when the coaster is at rest. (b) what is the minimum speed the coaster must have at the top of the loop in order for the rider to remain in contact with his seat? is this speed dependent on the mass of the rider? 8.

An alpha particle with kinetic energy 12.5 mev makes a collision with lead nucleus, but it is not "aimed" at the center of the lead nucleus, and has an initial nonzero angular momentum (with respect to the stationary lead nucleus) of magnitude l = p0 b, where p0 is the magnitude of the initial momentum of the alpha particle and b=1.40×10−12 m. (assume that the lead nucleus remains stationary and that it may be treated as a point charge. the atomic number of lead is 82. the alpha particle is a helium nucleus, with atomic number 2.) what is the distance of closest approach?
