Question

assuming that mass = 2150 kg

K = 80.98 N/mm

C =21.19 N/mm 

 

Please answer correctly please.

Question. In a car crash test, a car travelling at a constant speed of 60 km/h collides into a special replaceable block attached on a solid wall. We can simplify this process as a mass impacts on a spring-damper system in horizontal direction. If the stiffness and damping constant of the block are k and C respectively, and the mass of the car is given as m, determine: a) the time taken to reach that maximum displacement; b) the maximum displacement of the car after engaging the block (we can reasonably assume the car does not bounce back before it stops and ignore all frictions during collision). 0000 Crashlab B19022 0000 0000 ANCAP 19-HYU-5012-001 18 SEPT 2019
