A car is travelling on a straight highway where the speed limit is 110 km/h. You are watching it from a point 10 meters away from the road, and at the instance when the car is 20 meters directly away from you the angle that your line of sight makes with a perpendicular to the road increases at the rate of 3 4 radians/sec. Is the car breaking the speed limit? Fully justify your answer. (Note that 1 m/s =...

(1)Braking causes the vehicle speed to change from 98 km/hr to 23 km/hr over a distance of 97 m. Determine the angle of the hanging graduation tassel during this constant acceleration. Report the angle phi in degrees. (2) The tassel described in P1 has a mass of 42 g. A massless string secures the tassel to the rear view mirror. Determine the tension in the string under the braking conditions described in P1. Report the result in mili-Newtons.

A minor road intersects a major 4-lane divided road with a design speed of 55mph and a median width of 8 feet. The intersection is controlled with a stop sign on the minor road. If the design vehicle is a passenger car, determine the minimum sight distance required on the major road that will allow a stopped vehicle on the minor road to safely turn left if the approach grade on the minor road is 3%.
