Two cars drive on a straight highway. At time t=0, car 1 passes mile marker 0 traveling due east with a speed of 19.0 m/s . At the same time, car 2 is 1.2 km east of mile marker 0 traveling at 27.0 m/s due west. Car 1 is speeding up with an acceleration of magnitude 0.10 m/s2 , and car 2 is slowing down with an acceleration of magnitude 0.30 m/s2 . At what time do the cars pass...

Car 1 is speeding up with an acceleration of magnitude 0.30 m/s2 , and car 2 is slowing down with an acceleration of magnitude 0.50 m/s2 . At what time do the cars pass...
Two cars drive on a straight highway. At time t = 0, car 1 passes mile marker 0 traveling due east with a speed of 24.0 m/s. At the same time, car 2 is 1.2 km east of mile marker 0 traveling at 30.0 m/s due west. Car 1 is speeding up with an acceleration of magnitude 2.8 m/s^2, and car 2 is slowing down with an acceleration of magnitude 3.0m/s^2. At what time do the cars pass next to...
Two cars drive on a straight highway. At time t=0, car 1 passes mile marker 0 traveling due east with a speed of 20.0 m/s . At the same time, car 2 is 1.1 km east of mile marker 0 traveling at 28.0 m/s due west. Car 1 is speeding up with an acceleration of magnitude 0.30 m/s2 , and car 2 is slowing down with an acceleration of magnitude 0.40 m/s2. At what time do the cars pass next...
Two cars leave an intersection with car A traveling due west at a constant speed of 20 mph (as measured by the ground) and car B traveling at a constant speed of 30 mph in a direction of 57 south of east (also as measured by the ground). Determine the speed of car B as measured by car A.
At time, t=0s, car A is at rest at the origin of the coordinate system and car B is moving due east at a constant velocity of 20.0m/s. When car B is 50.0m west of car A, car A starts to move at a constant acceleration of 2.00m/s2 due east. how far from the origin has car a moved when car B overtakes car A. use graph of position vs time for both cars.
2. For each of the following motions draw a motion diagram, a position-vs-time graph, and a velocity-vs-time graph. a. A car starts from rest, steadily speeds up to 40 mph in 15s, moves at a constant speed for 30s, b. then comes to a halt in 5s A rock is dropped from a bridge and steadily speeds up as it falls. It is moving at 30 m/s when it hits the ground 3s later. Think carefully about the signs.
Consider two toy cars. Car A starts from rest and speeds up with constant acceleration for a time tA until it reaches a speed of vA and then continues to travel at this speed. At the moment car A reaches its maximum speed, car B, starting at rest from the same point that car A started from, speeds up with constant acceleration aB. a) Make a freehand plot of the speed of each car as a function of time. Label...
Solve the following problem. Show all your work At time t-0, a car has a constant velocity of 20.0 m/'s, east. At the same motorcycle starts from rest in the same direction with an acceleration o time a f 2.0 a) How long does it take the motorcycle to catch up with the car b) What distance have they traveled at that time?
