when it crashes into a bridge support that does not move a car goes from 95 km/h in 123m what is the impulse delivered to the 70 kg diver by the seat belt, assuming the belt makes the driver's motion identical to the car's motion assume that the initial direction of motion of the car is the positive direction. ​

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.

you get 2.3=1.21*\frac{a}2 or 4.6=1.21a or a=3.802 (b)
