In a quarter-mile drag race, two cars start simultaneously from rest, and each accelerates at a constant rate until it either reaches its maximum speed or crosses the finish line. Car A has an acceleration of 11.6 m/s2 and a maximum speed of 108 m/s. Car B has an acceleration of 11.7 m/s2 and a maximum speed of 91.0 m/s. Which car wins the race, and by how many seconds?

Chapter D2, Problem D2/095 GO Tutorial Incorrect Two cars travel at constant speeds through a curved portion of highway. If the front ends of both cars cross line CC at the same instant, and each driver minimizes his or her time in the curve, determine the distance δ which the second car has yet to go along its own path to reach line DD at the instant the first car reaches there. The maximum horizontal acceleration for car A is...

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...

Two cars A and B approach each other in two adjacent lanes of
a linear track in opposite directions, as shown in the figure. at t
= 0s, A and B are at D = 21m away, the car A departs from rest and
moves with a constant acceleration of aA = 2m / s ^ 2 and auto B
moves with constant velocity of Vb = 4m / s.
a) find the position based on time for both cars,...

Consider the following
two-caraccident: Two cars of equal mass collide at an intersection. Driver E was traveling
eastward, anddriver N, northward. After the collision, the two cars
remainjoined together and slide, with locked wheels, before coming
torest. Police on the scene measure the length of the skid marks to be 9 meters. The coefficient
offriction between the locked wheels and the road is equal to
0.9.
Each driver claims that hisspeed
was less than 14 meters per second (50 mph)....

Total: 20 pts) A car is braking hard. There are two significant resistive forces acting on it, a quadratic (cv2) air drag, and a constant (umg) frictional force. If you are interested in finding v(x) (rather than v(t)), there is a commonly used method known as the "v dv/dx rule”, which uses the chain rule to rewrite ü = = di = v . a) [12 pts) Write down the equation of motion for Ü = (v) and use the...
