Explanation:

32. The area under the curve from t = 0 and t = 2 is the area of the triangle.  The base of the triangle is 2 seconds, and the height of the triangle is 2 m/s.  The area is therefore:

A = ½ bh

A = ½ (2 s) (2 m/s)

A = 2 m

33. The car is not moving when the velocity is 0 m/s.  This occurs at t = 0, t = 6, and t = 10.
