A body is acted upon by a force of 10 N and undergoes a displacement in the direction of the force in accordance with the relation s = 3t³ + 2t, where s is the displacement in meters and t is in seconds. The rate at which the force is doing work at the instant t = 2 s is. The power developed by a certain engine is a function of time according to P= 2 + 3t² + 4t³ where the units are SI. The work done by the engine in the interval from t = 0 to t = 2 s is
