A 75,000 N weight truck hits the rear bumper of the 15,000 N weight car at a stop light. What
is the ratio of the collision force the truck puts on the car compared to the force the car puts on
the truck?
From Newton's 3rd law, the force of the truck on the car will be equal in magnitude to the force of the car on the truck.
Hence the required ratio is 1.

A 2300 kg truck has put its front bumper against the rear bumper of a 2400 kg SUV to give it a push. With the engine at full power and good tires on good pavement, the maximum forward force on the truck is 18,000 N. Part A What is the maximum possible acceleration the truck can give the SUV? Express your answer to two significant figures and include the appropriate units. a = Part B At this acceleration, what is...
A car rear-ends and sticks to a truck, and this question concerns their speeds just before and just after their collision (momentum is conserved). The car has a mass of 1000kg, the truck is 3000kg. Initially, the car is going 20m/s, but the truck is only going 5 m/s (coming from a stop light) in the same direction. Calculate the final speed of the car/truck combination after the collision.

Two bumper cars collide head on. Bumper car 1 has a weight of 150 lb and is moving with a speed of 6 ft/s. Bumper car 2 has a weight of 170 lb and is moving with a speed of 4 ft/s. If no energy is lost during the collision, A) what are the velocities of the two cars after the collision? B) What is the magnitude of the average force between the two cars during the collision if it...
A 2,900-kg truck runs into the rear of a 1,000-kg car that was stationary. The truck and car are locked together after the collision and move with speed 2 m/s. What was the speed of the truck before the collision?
A car is equipped with a bumper designed to absorb collisions. The bumper is mounted to the car using pieces of flexible tubing. Upon collision with a rigid barrier (e.g. brick wall), the bumper is designed so that a constant horizontal force is developed. If the car is initially traveling at 1.5 m/s when it collides with a rigid brick wall, compute the magnitude of the distance needed to stop the car and cause the deformation of the bumper tubing....
A 7,500-kg truck runs into the rear of a 1,000-kg car that was stationary. The truck and car are locked together after the collision and move with speed 7 m/s. Compute how much kinetic energy was "lost" in this inelastic collision.
A car going 25 m/s hits a stationary truck. Which of the statements are true? The magnitude of the force on the car is equal to the magnitude of the force on the truck The magnitude of the force on the car is greater than the magnitude of the force on the truck The magnitude of the force on the car is less than the magnitude of the force on the truck The car experiences an acceleration The truck experiences...
7. A 3 000 kg truck runs into the rear of a 1 000 kg car that was stationary. The truck and car are locker together after the collision and move with speed 9 m/s. What was the speed of the truck before the collision? 8. In the previous question determine if the collision was an elastic collision.
A truck moving at 35.0 mph collides head on with a car traveling in the opposite direction. The mass of the car is 550 kg, the mass of the truck is 2200 kg. During the collision both vehicles come to a stop in 0.150 s as the front end of both vehicles’ crumples. What was the acceleration of the car? Assume that during the collision the acceleration of each vehicle is constant. Also, assume that frictional force are small compared...
