The crate has a mass of 80 kg and is being towed by a chain which is always directed 20 degrees from the horizontal as shown. Determine the crate's acceleration in t=2 s if the coefficient of static friction is .4, the coefficient of kinetic friction is .3 and the towing force is P=90(t^2) N, where t is in seconds.
