A block of mass m₁ = 1.85 kg and a block of mass m₂ is 0.360 for both blocks. 5.90 kg are connected by a massless string over a pulley in the shape of a solid disk having a mass of M = 10.0 kg. The fixed, wedge-shaped ramp makes an angle of 0 = 30.0° as shown in the figure. The coefficient of kinetic friction m M, R m2 Ꮎ (a) Determine the acceleration of the two blocks. (Enter the magnitude of the acceleration.) m/s2 (b) Determine the tensions in the string on both sides of the pulley. left of the pulley right of the pulley N N
Consider as a system the Sun with Venus in a circular orbit around it. Find the magnitude of the change in the velocity of the Sun relative to the center of mass of the system during the time Venus completes half an orbit. Assume the mass of the Sun is 5.68 x 1029 kg, the mass of Venus is 4.87 × 1024 kg, its period is 1.94 × 107 s, and the radius of its orbit is 1.08 × 1011 m. Ignore the influence of other celestial objects. m/s
