Why is acceleration independant of mass??

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

Choose each of the settings that follow and list them below do it ill mark brainliest first object= position= speed= acceleration= second object= position= speed= acceleration=

A2k pendulum has a speed of 1 m/s at a height of 1/2 meter
