Did i put this in the right category??? 1. Let us say you are working in a crash test facility. The car you are testing hits the wall, the dummy is slumped over the wheel, and broken glass is everywhere. There is just one problem: your radar that measures the car’s speed was turned off!

You know that the length of your track is 15 meters. You also know that the car crossed the entire track in 0.5 second, because your high-speed cameras recorded the entire event. Use that information to answer the questions below.

What was the average velocity of the car during its test on the track?

2. Given the formula for impact force,

F = 2 x m x v / T

where F is force, m is mass, v is velocity, and t is duration of impact, what other data do you need in order to determine the force of the car at impact?

3. How might you measure this missing data?

As usual, any non-answers will be reported. Thank you!

I'm kinda lost ! 1. when marilyn takes her pet dog for a walk, the dog walks at a veryconsistent pace of 0.55 m/s. draw a position-time graph to representmarilyn's dog walking the 19.8 m distance from the front of her house tothe nearest fire hydrant.2. both car a and car bleave school when a stopwatch reads zero. car atravels at a constant 75 km/h, and car b travels at a constant 85 km/h. a) draw a position-time graph showing the motion of both cars. howfar are the two cars from school when the stopwatch reads 2 hrs? calculate the distances and show them on your graph. b) both cars passed a gas station 120 km from the school. when dideach car pass the gas station? calculate the times and show themon your graph.3. the figure below shows the position-time graph showing a shopper'smovement up and down the aisle at a store. a) write a story describing the shopper's movements at the store. b) when does the shopper have a position of 6 m? c) how much time passes between when the shopper enters the aisleand when he gets to a position of 12 m? what is the shopper's averagevelocity between 37 s and 46 s?

Modern physics a photon emitted from an excited hydrogen atom has an energy of 3.02 electron volts. which electron energy-level transition would produce this photon? a. n=1 to n=6 b. n=2 to n=6 c. n=6 to n=1 d. n=6 to n=2 i chose b but the correct answer is d can someone tell me why? and what's the difference?

1.what is where an object is located 2. what is how fast an objects speed is changing 3. what is how fast an object is moving
