PLEASE HELP!! THANKS ASAP - I uploaded the photos

I don't think they are in the right order but the one with the photo is the first one

Determine the amount of work done when a crane lifts a 100-n block form 2m above the ground to 6m above the ground

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

The dot diagram represents the motion of the motorcycle as it moves from left to right
