A force acts on a 3.283 kg mass as follows: the force starts at zero and rises to 35.245 N linearly in 1.912 seconds, it remains at 35.245 N for

another 6.964 seconds, then diminishes linearly to zero in 1.048 second. If the mass had an initial velocity of 0 m/s, what is the final speed of the mass after the impulse?
