Car A was traveling east at high speed when it collided at point with car B,...
2. A driver is traveling at 90 mi/h down a 3% grade on good, wet pavement. An accident investigation team noted that braking skid marks started 410 ft before a parked car was hit at an estimated 45 mi/h. Ignoring air resistance, and using theoretical stopping distance, a. what was the braking efficiency of the car? b. If the car’s antilock braking system was effective (no sliding wheels on the pavement), what would the crash speed be?
A 900-kg car traveling east at 15.0 m/s collides with a 750-kg car traveling north at 20.0 m/s. The cars stick together. Assume that any other unbalanced forces are negligible. a. What is the speed of the wreckage just after the collision? b. In what direction does the wreckage move just after the collision? c. How much kinetic energy is lost in this collision.
A 900 Kg car is traveling east at 15 m/s when it collides with a 750 Kg car traveling north at 20 m/s. The cars stick together. What is the kinetic energy of the system after the collision?
Two cars, both of mass m, collide and stick togetber. Prior to the collision, one car had been traveling north at speed 2v, while the second was traveling at speed u at an angle φ south of east (as indicated in the figure). After the collision, the two-car system travels at speed vfinal at an angle θ east of north.
Two cars, both of mass m, collide and stick together. Prior to the collision, one car had been traveling north at speed 2v, while the second was traveling at speed v at an angle phi south of east (asindicated in the figure). After the collision, the two-car system travels at speed v_final at an angle theta east of north.Part AFind the speed v_final of the joined cars after the collision.Express your answer in terms of v and phi.Part BWhat is...
Two cars are latched together with a speed of 3 m/s traveling to the east when they catch up and collide with another car moving at a speed of 0.6m/s east. If the three-car latches to the other two. How fast will the three cars joint together after the collision happens? Same Mass for all vehicles.
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)...
1. A pole is held vertically by attaching wires at a height of 13.4 m above the ground. The other end of each wire is anchored in the ground at a distance of 9.54 m from the base of the pole. The pole makes a right angle with the ground. What is the length of each wire? 2. A bug crawls 2.25 m along the base of a wall. Upon reaching a corner, the bug's direction of travel changes from...
