A car in the left lane of a highway is trying to pass a truck in the right lane. The front of the car is initially 70.0 m behind the front of the truck. The car moves at a constant speed of 65.0 km/h, while the truck moves at a constant speed of 20.0 km/h. How long (in s) does it take the car to overtake the truck (that is, for the front of the car and the front of...
64. A truck is initially traveling on a highway at constant speed. The driver wishes to pass an automobile and so begins a 30-s period of constant acceleration at 0.050 m/s2. During this period, the truck travels 700 m. What was the truck's initial speed? The truck's final speed?
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...
A driver operating a vehicle at a speed of 25.0 m/s intends to pass a second vehicle 2.00 km ahead traveling in the same direction with a speed of 30.0 m/s. The driver of the first vehicle accelerates at a uniform rate to pass the second vehicle, and does so after traveling 4.00 km. Thus, whereas the first (rear) vehicle traverses 4.00 km, the second (front) car only travels 2.00 km, when it is passed. If the driver of the...
anything helps!!
Question 1 5 pts Consider two cars traveling on the highway, one behind the other. They are both moving at the same initial velocity, v 29.1 m/s, with the first car a distance d in front of the second car. ("d" is the distance from the front bumper of the second car to the back bumper of the first car.) At some time the driver of the first car hits the brakes and comes to a stop with...
1. A car is traveling south at 25 mi/hr (11.4 m/s). A truck having four times the mass of the car is traveling east at 50 mi/hr (22.7 m/s). How many times greater is is the trucks kinetic energy compared to the cars kinetic energy? explain your reasoning. 2. A car having a mass of 1900 kg strikes a smooth, rigid post with an initial speed of 8.3 m/s. the sign does not mover but the bumper of the car...
A car sits in an entrance ramp to a freeway, waiting for abreak in the traffic. The driver sees a small gap between a van and an 18-wheel truck and accelerates with constant acceleration along the ramp and onto the freeway. The car starts from rest, moves in a straight line, and has a speed of 21.0 m/s when it reaches the end of the ramp, which has length 124 m . 1- What is the acceleration of the car?...
A truck of mass 2.40×103 kg is moving at 25.0 m/s. When the driver applies the brakes, the truck comes a stop after traveling 48.0 m. a) How much time is required for the truck to stop? b) What is the magnitude of the truck's constant acceleration as it slows down?
When the drivers pass each other, the driver of the red car is
to toss a package of contraband to the other driver. To catch the
toss on video, one of the cameras must be set up near the point
where the toss will be made. When “action” is yelled out on the
set, the initial separation between the drivers will be 200 m, the
red car will accelerate from rest at a constant 6.12
m/s2, starting at xr =...
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
ft and vA = vB, determine (a) the
acceleration aA, (b)...
