A 136-kg crate is subjected to the forces shown. If it is originally at 1, determine the amount of energy (in J) lost due to friction (i.e. the work of friction) after the crate attains a speed of v=9m. Coefficient of kinetic friction is μ = 0.2 Hint: find out how far the box travels first. 500 N 400 N 45° 30°
