7. A 68kg cart that was originally at rest starts moving once an 65.5 N force is applied. After 10 seconds, the cart has achieved a velocity of +5.5 m/s. If the same force is applied for the duration of the time, then calculate the magnitude of the cart's new momentum. A. 0.00 kg*m/s B. 55 kg*m/s C. 360 kg*m/s D. 374 kg*m/s​
