55-kg crate shown in the figure rests on a horizontal surface for which the coefficient of kinetic friction is ??= 0.55−0.09? where ? is the time in seconds. If the crate is subjected to a constant 500-N towing force as shown, determine the velocity in m/s and the acceleration in m/s2 of the crate in 3s starting from rest. Hint: integrate.
