A 654-kg car stopped at an intersection is rear-ended by a 1500-kg truck moving with a speed of 14.3 m/s. If the car was in neutral and the brakes were not applied, so that the collision is approximately elastic, find the final speed of both vehicles after the collision.

However, the question is not clear due to the presence of numerous typographical errors and unclear abbreviations. In order to provide a solution, we need to know the mass of the car and the truck, the initial speed of the truck, and whether the collision is Show more…

13. Suppose a truck with mass m = 2200 kg has a head-on collision with a subcompact car of mass m = 1100 kg. a) At the collision, a truck exerts a force of 2.9 * 10^4 N on the subcompact car. If the absolute value of the acceleration experienced by the truck and the subcompact car is called as atruck and acar, respectively, then find the relationship between atruck and acar. b) At the time of a head-on collision, each vehicle has an initial speed of 15 m/s and they are moving in opposite directions (one in +x direction and the other in -x direction). The two cars crash into each other and become entangled. What is the final velocity? c) What is the velocity change for the truck: d) What is the velocity change for the car:

Car A is traveling at 40 km ∕hr and applies the brakes at the position shown so as to arrive at the intersection C at a complete stop with a constant deceleration. Car B has a speed of 65 km ∕hr at the instant represented and is capable of a maximum deceleration of 5 m ∕sec2. If the driver of car B is distracted and does not apply his brakes until 1.30 seconds after car A begins to brake, the result being a collision with car A, with what relative speed will car B strike car A? Treat both cars as particles.

A car with mass 1.45x103 kg is traveling due South at an unknown speed when it collides at an intersection (one of those weird five-way intersections) with an 8.24x103 kg-truck traveling 25° North of East also at an unknown speed. The wreckage then proceeds due East, coming to a halt in 12.5 m. If the coefficient of friction between the road and the car/truck-combo is 0.722, how fast was the car moving prior to the collision? 2.As a forensic medical examiner, you need to find fault with this accident. Generally, the driver moving faster is at fault. So … who’s fault was it, the driver of the car or the truck? Defend your answer with a specific calculation.
