13-10. 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. Determine the crate's acceleration in / = 2 s if the coefficient of static friction is fx, = 0.4, the coefficient of kinetic friction is fik = 0.3. and the towing force is P = (90r) N. where t is in seconds.
