The crate has a mass of 80 kg and is being towed by a chain which is always directed at 20° from the horizontal as shown. If the magnitude of P is increased until the crate begins to slide, determine the crate's initial acceleration if the coefficient of static friction is = 0.5 and the coefficient of kinetic friction is pk = 0.3. 13
