A 5,000 kg truck traveling at 50 m/s encounters a wall and comes to a stop as it crashes into the wall. The force of the crash was 60,000 N. How long was the crash?
n a crash test, a truck with mass 2000 kg traveling at 23 m/s smashes head-on into a concrete wall without rebounding. The front end crumples so much that the truck is 0.62 m shorter than before. (a) What is the average speed of the truck during the collision (that is, during the interval between first contact with the wall and coming to a stop)? vavg= m/s (b) About how long does the collision last? (That is, how long is...

happen to the momentum of the truck if it increases in velocity in
the same direction?

A 2 kg mass traveling at 5m/s undergoes a constant acceleration and comes to a stop in 10 seconds. a) what acceleration does it experience? b) how far does it go during the time it is coming to a stop? c) What net force does the mass experience as it comes to a stop? A 75 kg mass accelerates from rest at a rate of 2m/s2 over a distance of 50m a) How fast is it going after covering a...
A 1500-kg car traveling east at 50 m/s collides with a 2200-kg truck traveling north at 66 m/s. The car and truck become entangled and slide to a stop. What is the final speed immediately after the collision? What angle with respect to the east direction do the entangled vehicles slide?
A 750 kg car slows to a stop from traveling southbound at 30 m/s over a distance of 500 m. What was the acceleration needed to stop the car? How large was the force required to stop the car? Two cables are being used to pull a 100 kg sled on a frictionless surface. The first cable has a tension of 500 N in a direction 15o south of east. The other cable has a tension of 800 N in...
How long does it take an automobile traveling in the left lane of a highway at 50.0 km/h to overtake (become even with) another car that is traveling in the right lane at 35.0 km/h when the cars' front bumpers are initially 55 m apart? s
A 10 kg box is pushed from rest by a truck for 2m. Once the truck stops pushing the box it is traveling 6 m/s.This box slides for 5 seconds before coming to a stop. If the specific heat is 2 joules per degree kg, how much did the temperature of the box change by and what is the average force applied by the truck?
A 5 m long truck is traveling at 100 km/h. How long will the truck appear to a stationary observer standing by the side of the highway?
A 1200·kg car traveling with a velocity of 12·m/s north collides head-on with a 2400·kg truck traveling with a velocity of 8·m/s south. Immediately after the collision, the velocity of the car is 4·m/s south. Take north as the positive direction (a) What is the velocity of the truck immediately after the collision? (b) What impluse is delivered to the car by the truck? (c) What impluse is delivered to the truck by the car?
