**1. Homework Statement**

A car moving at 30 m/s has a collision and comes to rest in 0.1 seconds. The driver, ClarkGriswold, is brought to rest by an air bag in 0.13s. The driver has a mass of 50 kg.

1) What average force is exerted by the air bag on the driver ?

3) How far does the driver travel while stopping?

4) Two suitcases fly off the roof of the carmoving at 12 m/s relative to the groundand the lid of one pops open, pushingthem apart. The opened suitcase, with amass of 20 kg, is moving at 6 m/s afterthey separate. If the second suitcase hasa mass of 15 kg, what is its velocityafter they separate? https://gyazo.com/59d8533684d27020728eb27ae61cf85d.jpg [Broken]

**3. The Attempt at a Solution**

1) I assume you use impulse = change (f*t=m*change in v)) in momentum to find the force, but my teacher been talking about using energy to solve stuff, so I don't know if I can use energy formula to solve it somehow? also my answer using impulse = change in momentum equation give me 11538.46 N

3) Is it easy as multiplying the speed to the .13s? (30m/s*0.13s)

4) wouldnt the red suitcase continues flying at 12m/s?
