Q. The velocity graph of a car accelerating from rest to a speed of 60 km/h over a period of 30 seconds is shown. Approximation the distance, d travelled throughout this period. (Use M6 to get the most precise estimate. Round the answer to two decimal places.) This graph looks like 1/4 of an ellipse with the x-axis being time and the y-axis being velocity.

Q. A 2.06 kg particle has a velocity (2.07 ihat - 3.01 jhat) m/s, and a 2.97 kg particle has a velocity (0.94 ihat + 6.05 jhat) m/s.

(1) Find the velocity of the center of mass.

(2) Find the total momentum of the system.
