Q1. Two automobiles of equal mass approach an intersection. One vehicle is travelling with velocity 13 m/s toward the east and the other is travelling north with speed v2i. Neither driver sees the other. The vehicles collide in the intersection and stick together, leaving parallel skid marks at an angle of 55.0 north of east. The speed limit for both roads is 35mi/h, and the driver of the northward-moving vehicle claims he was within the speed limit while the collision occurred. Is he telling the truth?

Q2. A 4.5 kg ham is thrown into a stationary 15kg shopping cart. At what speed will the cart travel if the ham had an initial speed of 2.20m/s?
