a) Two identical balls (mass m, radius r) roll with (translational or CM) velocity v along a flat surface. The balls then roll up inclines, one incline has friction, the other does not. Prove which ball reaches higher up its ramp. b) Imagine a pulley wheel of mass mp and radius rp, and suspended over this pulley are two masses, m1 and m2. If m2 > m1 and m1 starts from rest at a position h lower than m2, how...

2) Two solid rubber balls (one of mass m and radius r, and the other of mass M and radius R) roll without slipping up an incline. They are, initially, moving at 7.0 m/s. Eventually, they stop for a split second and then start to fall back down. Which ball goes higher? (15 points. Hint: find KE and Rotational KE for both). Calculate the height that each will reach (5 points). Hint: Use conservation of total mechanical energy). The moment...

Two small pith balls, each of mass m = 17.1 g, are suspended from the ceiling of the physics lab by 0.4 m long fine strings and are not moving. If the angle which each string makes with the vertical is θθ = 37.7°, and the charges on the two balls are equal, what is the magnitude of that charge (in µC)? (Please note that the unit of charge is micro-Coulomb here - some browsers might not display the Greek...

H Collision Between Two Balls Part A Two identical steel balls, each of mass 3.20 kg, are suspended from strings of length 31.0 cm so that they touch when in their equilibrium position. We pull one of the balls back until its string makes an angle 0 = 52.0° with the vertical and let it go. It collides elastically with the other ball. How high will the other ball rise? m п Submit Answer Tries 0/5 Part B Suppose that...

2. A uniform, solid cylinder with mass M and radius 2R is on an incline plane with angle of inclination of 6. A string is attached by a yoke to a frictionless axle through the center of the cylinder so that the cylinder can rotate about the axle. The string runs over a disk-shaped pulley with mass M and radius R that is mounted on a frictionless axle through its center. A block of mass M is suspended from the...

Two charged pith balls are suspended on very light 120 cm strings. Each has a mass of 10.0 g. Assume the angle the threads make from the vertical is 0 -10 and that the balls are in equilibrium. Draw a free-body diagram for one of the pith balls and clearly label all forces with magnitude and direction. Assuming the pith balls are equally charged, what is he charge on each ball? (This qualitative predicti obtained.) is is not a qualitative...
