C.) speed and weight of the vehicle
D.) all of the above
Get the Correct ANSWER
all of the above
Explanation: The amount of energy that's absorbed by the vehicle is related to both the vehicle's design and the direction of the impact. More and more high tech research and development is being conducted to make cars safer and more reliable.

Laws of Motion
A car crushing in a collision absorbs some of the force of the crash.
A.) TRUE
B.) FALSE
Get the Correct ANSWER
TRUE
In a motor vehicle crash, as a car crushes, it absorbs some of the force of the collision.
A.) TRUE
B.) FALSE
Get the Correct ANSWER
TRUE
Explanation: Especially, cars are intended to crush and consume some of the collision. However, they cant crumple too enough or our legs will get crushed also, which is not good. Its all based on the postulate that the force of the collision is less if the entire deceleration takes place over a prolonged duration of time. The car crumpling tries to increase the deceleration time.
