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!

Determine el momento angular de un rueda de 3000g moviendose a 10m/s con un radio de giro de 400cm

Amass attached to a spring is displaced from its equilibrium position by 5cm and released. the system then oscillates in simple harmonic motion with a period of 1s. if that same mass–spring system is displaced from equilibrium by 10cm instead, what will its period be in this case? a mass attached to a spring is displaced from its equilibrium position by and released. the system then oscillates in simple harmonic motion with a period of . if that same mass–spring system is displaced from equilibrium by instead, what will its period be in this case? a) 0.5sb) 2sc) 1sd) 1.4s

How are elastic and inelastic collisions different? give two or more ways. your answer should have at least 2 sentences.
