The magnitude of the net force exerted in the x direction on a 2.50-kg particle varies with time as shown in the force-time curve. Find: (a) the impulse of the force over the 5.00-s time interval; (b) the final velocity the particle attains if its originally at rest; (c) its final velocity if its original velocity is -2.00i m/s; and (d) the average force exerted on the particle for the time interval between 0 and 5.00 s.
