Question

The man slides the 100-kg crate across force of 200 N. If the crate was initially at rest, how far will the crate move before
its speed is 1 m/s? The coefficient of kinetic friction between the crate and the
floor is 0.18.

The man is pulling the crate at a 20 degree angle.

Answer 1

net force=200cos20-(100*9.8-200sin20)*.18

but net force= 100*acceleration
solve for acceleration

then vf^2=vi^2+2ad solve for d
