Find the center of mass of the region bounded by y = x and y = x2. Hint: We have talked about center of mass in one direction here you area asked for the center of mass of the 2-dimensional region. Find the center of mass along the x-axis, as well as the y-axis?

Natural forces that can alter ecosystems include seasons and climate changes. t or f

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

Could someone . i have tried to solve myself but my calculation is off
