In astronomy, the term perihelion refers to the point in the orbit of an asteroid, comet, or planet at which it is closest to the sun. aphelion refers to the point at which the object is furthest away from the sun. research facts about the dwarf planet ceres. calculate the average orbital speed of ceres in miles/hour when it is closest to the sun and when it is farthest away.

The motor m applies a time-varying force of f (200 t) n, where t is in seconds. box b with mass 200 kg starts from rest, and the coefficients of kinetic and static friction are 0.2 and us 0.3 the acceleration due to gravity is g 9.8 m/s2 b 300 a) find the time ' when the box starts to move. b) calculate the speed of the crate at 3 s c) calculate the power delivered by the motor at t 3 s
