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 = 18 5 km/h.)

The existing posted speed limit on a section of highway is 88 km/h and studies have shown that the current 85th percentile speed is 104 km/h. If the posted speed limit is to be increased to the current 85th percentile speed, what should be the increase in the radius of a curve that is just adequate for the existing posted speed limit? Assume a superelevation rate of 0.08 for the existing curve and for the redesigned curve.

A car has a mass of 2000 kg which was travelling east but now has collided with truck with mass of 2500 kg which was travelling north. After the collision we see that the cars are stuck together and have slid 7.7 meters northeast at a 40 degree angle. The car driver claims the accident happened because the truck was speeding; the truck driver claims the car was speeding. The posted speed limit is 35 miles/hour. Determine from the location...

A police officer in a helicopter is hovering 1110 feet directly over a straight stretch of I-5 where the speed limit is 70 miles per hour. A car passes below very quickly so the officer pulls out the radar gun. At the moment of using the radar the results show that the car is 1985 feet away from the helicopter, and it is moving away from the helicopter at 95 feet per second. The helicopter officer notifies the ground patrolman...
