A car in the left lane of a highway is trying to pass a van in the right lane. The front of the car is initially 115 m behind the front of the van. The car moves at a constant speed of 70.0 km/h, while the van moves at a constant speed of 40.0 km/h. How long (in s) does it take the car to overtake the van (that is, for the front of the car and the front of the van to be even with each other)?
____ (s)
Homework Answers
Here we need to calculate that in how much time relative speed will cross the relative distance
Relative speed =70-40=30km/h=8.33m/s
Relative distance = 115m
Thus time = 115m/8.33m/s
t=13.81s

Car A is parked along the
northbound lane of a highway, and car B is traveling in the
southbound lane at a constant speed of 60 mi/h. At t = 0, A starts
and accelerates at a constant rate aA, while at t = 5 s,
B begins to slow down with a constant deceleration of magnitude
aA/6. Knowing that when the cars pass each other x = 294

Question 8 1 pts The driver of a car wishes to pass a truck that is traveling at a constant speed of 20.0 m/s. Initially, the car is traveling at a speed 25.0 m/s and its front bumper is a distance 24.0 m behind the truck's rear bumper. The car begins accelerating at a constant acceleration 0.6 m/s2, then pulls back into the truck's lane when the rear of the car is a distance 26.0 m ahead of the front...

You are driving along the highway at a steady speed of 90 km/h when another car decides to pass you. At the moment when the front of his car is exactly even with the front of your car, and you turn your head to smile at him, do the two cars have equal velocities? Draw a position graph to describe the motion of two cars.

Exercise 1 [I8 pts]. Two lanes of a three-lane highway are closed because of road works on a 2 km long segment. A detector placed on one single lane in the undisturbed zone upstream the road works detects a flow of 2,000 veh/h and an average speed of 100 km/h. A second detector placed on one of the two lanes just upstream the roadwork zone detects a flow of 800 veh/h and an average speed of 40 km/h. We observe...

The traffic on a two-way two-lane highway is assumed to follow Greenberg model. The average headway at Capacity is 1.9 seconds while the average spacing at jam conditions is 9 meters. At 9:00 AM on a typical weekday, two platoons were travelling on the highway in the eastbound direction. The length of the first platoon is 3 km and the average vehicle speed in this platoon is 62 km/h. The second platoon is a long platoon that starts directly to...
