At the instant shown, the car at A is traveling 10 m/s at 45° SE around the curve with radius of curvature of 100 m, while increasing its speed at 8 m/s sq. The car at B is traveling at 18.5 m/s along the straightway eastward and increasing its speed at 5 m/s sq. Determine the relative velocity and relative acceleration of B with respect to A at this instant. The normal component of acceleration for car A makes a 45° with the horizontal axis at the center of curvature. Show the proper units in all cases.

1.Determine the relative velocity, in vector form, of B with respect to A

2.Determine the direction (angle and sense) of the relative velocity of B with respect to A. Indicate the sense as SW (southwesterly), SE (southeasterly), NW (northwesterly) or NE (northeasterly).

A car is traveling along a straight road at a velocity of +35.0 m/s when its engine cuts out. For the next ten seconds the car slows down, and its average acceleration is a1. For the next five seconds the car slows down further, and its average acceleration is a2. The velocity of the car at the end of the fifteen-second period is +24.2 m/s. The ratio of the average acceleration values is a1/a2 = 1.78. Find the velocity of...
