Two vehicles approach a right angle intersection and then suddenly collide. After the collision, they become entangled.

If their mass ratios were 1:4 and their respective speeds as they approached the intersection were both 13 m/s, find the magnitude and direction of the final velocity of the wreck.
A) 11 m/s at 76 with respect to the original direction of the lighter car
B) 26 m/s at 76 with respect to the original direction of the lighter car
C) 16 m/s at 14 with respect to the original direction of the lighter car
D) 16 m/s at 76 with respect to the original direction of the lighter car
E) 11 m/s at 14 with respect to the original direction of the lighter car

Question 2

Water, which we can treat as ideal and incompressible, flows at 12 m/s in a horizontal pipe with a pressure of 3.0 104 Pa. If the pipe widens to twice its original radius, what is the pressure in the wider section?

A) 9.8 104 Pa B) 3.0 104 Pa C) 7.4 104 Pa D) 4.9 104 Pa
