The amount of energy absorbed by a vehicle in an impact is related to a. the direction of the impact. b. the design of the vehicle. c. all of the above

The correct answer is "The amount of energy absorbed by a vehicle in an impact is related to C. all the above."

Explanation:

The direction of the impact and the speed affects the amount of energy absorved and that is why during testings, there are different categories like longitudinal vs transverse impact testing.

Also, the design of the vehicle is made according to the tests in order to  absorbe as much amount of energy as posible and keep the passengers safe. This is called programmed deformation zones.

total distance travelled = 60 miles

total time taken =1.5 hours

average speed = total distance / total time

60 / 1.5

= 40

therefore, average speed = 40 m/h
