Determine the acceleration of the object at t = 2 seconds (check a@t=0 is -90): Clear[t, v, x] x[t] x[0] x[2]//N Find the maximum acceleration of the object: Solve[0, t] x[]//N In a boat race, boat A is leading boat B by L = 50 "m" and both boats are traveling at a constant speed of 252 km/h. At t = 0, B accelerates at a constant rate of 2 m/s^2 while A maintains its original velocity. Find the time and position that B passes A.
