A particle (M1 = 1.47 kg) moving at 30.0° downward from the horizontal with v1 = 2.53 m/s hits a second particle (M2 = 3.47 kg), which is at rest. After the collision, the speed of M1 is reduced to 0.541 m/s, and it is moving at an angle of 32.0° downward with respect to the horizontal. You cannot assume that the collision is elastic. What is the speed of M2 after the collision?
Consider two widely separated conducting spheres, 1 and 2, the second having four times the diameter of the first. What is the ratio of the final surface charge density of spheres
A 2500 kg car rounds a flat curve of radius 75 m at speed of 80 km/h. if the pavement is icy and the force of static friction is 6000 n, what is the maximum speed the car could safely go around the curve
15 points A block of mass 5.00 kg is pushed from a height of 2.00m inside of a frictionless circular hoop of radius 2.00m. What is its speed at the lowest point
What harm, if any, would occur by rotating the spectacle lenses of a near-sighted person in their frames? What if the individual had an astigmatic correction
Speedboat A negotiates a curve whose radius is 152 m. Speedboat B negotiates a curve whose radius is 204 m. Each boat experiences the same centripetal acceleration. Illustrate what is the ratio vA/vB of the speeds of the boats?

Mary needs to row her boat across a 100-{rm m}-wide river that is flowing to the east at a speed of 1- {rm m/s}. Mary can row the boat with a speed of 2- {rm m/s} relative to the water.
Two boats are heading away from shore. Boat 1 heads due north at a speed of 3.77 m/s relative to the shore. What is the speed of the passenger relative to the shore
A hotel elevator ascends 170 m with a maximum speed of 5.9 m/s. Its acceleration and deceleration both have the magnitude of 1.5 m/s2.
An AC voltage of the form ?V = (85 V) sin (330 t) is applied to a series RLC circuit. If R = 42 ?, C = 29 µF, and L = 0.3 H, find the rms current in the circuit
If the curve were not banked, elucidate the minimum coefficient of friction between tires and road that would keep traffic from skidding out of the turn when traveling at 97 km/h?
A diving board of length 3 is supported at a point 1 from the end, and a diver weighing 480 stands at the free end. The diving board is of uniform cross section and weighs 295.
