4. Using the facts from question 1, imagine there was a person, unseat-belted, in the car. The person weighs 70 kg. What speed would the person be traveling at compared to the car after the collision? Explore two possibilities, and explain your reasoning fully. (Hints: Is the person part of or separate from the vehicle in terms of motion? How does the mass of the person change the problem?) Do your best!

Ahonda civic travels in a straight line along a road. its distance x from a stop sign is given as a function of time t by the equation x(t)= î± t2â î² t3, where î± = 1.53 m/s2 and î² = 5.50ã10â2 m/s3 .

Mass (kg) force (n) 5 25 10 50 15 75 20 100 a student was trying to find the relationship between mass and force. he placed four different masses on a table and pulled them using a spring scale. the table shows the different masses used in the experiment and the force required to pull each mass. the student concluded that more force was required to pull heavier objects. what comment would you make regarding his conclusion? a) no clear relation can be observed between mass and force from the data. b) there is a direct proportion between the mass and force listed in the table. c) gravity should have been taken into account while performing the experiment. d) there is an inverse proportion between the mass and force listed in the table.
