Calculate the work required to move a planet’s satellite of mass 571 kg from a circular orbit of radius 2r to one of radius 3r, where 8.8 × 106 m is the radius of the planet. the mass of the planet is 7.76 × 1024 kg. answer in units of j]

An object moves from position +34m to the position -15m in 15 seconds. what is the total displacement? what is the total velocity?

Aturntable a is built into a stage for use in a theatrical production. it is observed during a rehearsal that a trunk b starts to slide on the turntable 10 s after the turntable begins to rotate. knowing that the trunk undergoes a constant tangential acceleration of 0.31 m/s2, determine the coefficient of static friction between the trunk and the turntable.
