A train which is traveling at 73 mi/hr applies its brakes as it reaches point A and slows down with a constant deceleration. Its decreased velocity is observed to be 56 mi/hr as it passes a point 1/2 mi beyond A. A car moving at 36 mi/hr passes point B at the same instant that the train reaches point A. In an unwise effort to beat the train to the crossing, t the driver "steps on the gas." Calculate the...

a. Two cyclists racing on parallel roads maintain constant speeds of 30 mi/hr and 25 mi/hr. The faster cyclists crosses the finish line one hour before the slower cyclist. How long was the race (in miles)? b. Because Boat A travels 1.5 times faster than Boat B, Boat B was given a 1.5-hr head start in a race. How long did it take Boat A to catch Boat B? c. A plane flew into a headwind and made the outbound...

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)...

Ralph is driving at a constant 70.0 mi/hr (31.3 m/s) along a straight section of Route 3 North. The car directly ahead of him is also moving at 70.0 mi/hr. The front bumper of Ralph's car is located 12.00 m from the rear bumper of the car ahead when, at t0, the driver of the car ahead applies his brakes and begins to slow down at a steady rate of 6.00 2, towards the posted speed limit of 50.0 mi/hr...

Can someone help me with number 2. Thank you
. A van traveling 60 mi/hr sees a duck in the distance and slams on its brakes. If the duck is exactly 3 feet away when the van begins braking, how quickly must it accelerate in order to save c. A duck on a motorcycle is speeding down the highway at 65 mi/hr where the speed limit is 00 the duck? only 55 mi/hr. It passes a police car on the...

Problem A car travels at a constant speed of 29.5 mi/h (13.2 m/s) on a level circular turn of radius 46.0 m, as shown in the bird's-eye view in Figure 7.13a. What minimum coefficient of static friction, Aus, between the tires and the roadway will allow the car to make the circular turn without sliding? Strategy In the car's free-body diagram (Fig. 7.13b) the normal direction is vertical and the tangential direction is into the page (step 2). Use Newton's...
