a force of 1600N is used to push a crate of brick at a rate of 40m/s squard. If the crate weights 150kg, how much do the bricks weight?
f=(total mass)a
total mass=masscrate+massbricks=1600/40
massbricks=40-mass crate, and at this point, the problem is flawed, the mass of brick cannot be negative, nor the weight (mass*g) be negative.
Recheck your probleml.
