At a crash test facility scientists run a car of mass m into a wall at a velocity v. The car comes to rest following the collision. The experiment is repeated several times at the same velocity for several different cars (all of mass m). Given that the mass of the cars and the velocity of the cars are all the same, the only way to alter the average force exerted on the passenger is to change the duration of the collisions.Which of the following features of cars/roads act to increase the collision time directly (i.e. while a collision is occurring)? Question 5Select one or more:a.Air Bagsb.Anti-lock brakesc.Headlightsd.Water/sand Barrels

At a crash test facility scientists run a car of mass m into a wall at a velocity v. The car comes to rest following the collision. The experiment is repeated several times at the same velocity for several different cars (all of mass m). Given that the mass of the cars and the velocity of the cars are all the same, what aspect of the collision can a car designer try to change to reduce the average force applied to the car (and hence to the occupants of the car)? Question 4Select one: a. Duration of the collision b. Change in momentum of the cars c. Force of the car on the ground d. Momentum of the cars e. The force of the wall on the ground

In a collision between two vehicles of different masses, which vehicle experiences the greater change in velocity?(1 Point)The heavier vehicleThe lighter vehicleBoth experience the same changeIt depends on the speed of impact

Car B of mass 1200 kg is stationary. Car of mass 20 kg is travelling towards car B at 18 m/s. The cars collide and car B experiences an impulse. car A continues to move in the same direction, with a momentum of 21000 kgm/s. (i) calculate the momentum of car B immediately after the Collision. (II) Determine the average impulse experienced by car b during the Collision. (III) The cars are in contact for 0.20 s. Calculate the average resultant force experienced by car B during the collsion

12. Force of impact is determined by all of the following factors, except: A. Impact distance B. Driving experience C. Vehicle weight D. Speed of vehicle
