An automobile P is traveling along a circular track of radius R=958.4 m. At position "A" on the track, the automobile has a speed of UA = 10.3 m/s. At this position, the driver of the automobile applies the brakes causing the speed of the automobile to change with distance s traveled along the track according to the following equation: v(s) = VA cos(0.001s) m/s (cos is in radians), where s is given in meters. Determine the magnitude of the acceleration for the driver when the automobile reaches position "B" on the track where "B" is a quarter of the distance around the track from position "A". B

Question
Transcribed Image Text:An automobile P is traveling along a circular track of radius R=958.4 m. At position "A" on the track, the automobile has a speed of UA = 10.3
m/s. At this position, the driver of the automobile applies the brakes causing the speed of the automobile to change with distance s traveled along
the track according to the following equation: U(S) = VA COS(0.001s) m/s (cos is in radians), where s is given in meters.
Determine the magnitude of the acceleration for the driver when the automobile reaches position "B" on the track where "B" is a quarter of the
distance around the track from position "A".
