1. What is the relationship between the length of time a force has an impact on an object and the impulse exerted on the object?
2. In a car crash why is it advantageous for an occupant to hit an airbag rather than the steering wheel? Explain your reasoning in terms of impulse, force, and time.
3. If the popper took four times longer to snap, what would've happened to the force of the snap? What data would you reference as evidence to support your reasoning?

Imagine you are riding on a yacht in the ocean and traveling at 20 mph. you then hit a golf ball at 100 mph from the deck of the yacht. you see the ball move away from you at 100mph, while a person standing on a near by beach would observe your golf ball traveling at 120 mph (20 mph + 100 mph). now imagine you are aboard the hermes spacecraft traveling at 0.1c (1/10 the speed of light) past mars and shine a laser from the front of the ship. you would see the light traveling at c (the speed of light) away from your ship. according to einsteinβs special relativity, how fast will a person on mars observe the light to be traveling? a) 0.1c (1/10 the speed of light) b) c (the speed of light) c)1.1c (c+0.1c)
