A car moving at 30 m/s slows uniformly to speed 10 m/s in a time of 5sec. Determine that distance it moves in the third second.

Sophia is cruising at 28.0 m/s down Lake Avenue and through the forest preserve. She notices a deer jump into the road at a location 62.0 m in front of her. Ima first reacts to the event, then slams on her brakes and decelerates at -8.10 m/s2, and ultimately stops a picometer in front of the frozen deer. What is Ima's reaction time? (i.e., how long did it take Sophia to react to the event prior to decelerating?

Given the position vs time graph on the left, discuss and plot the associated velocity vs time and speed vs time graphs.

What is the SI unit of instantaneous speed? Select one: O m/s. m's m. O m/s. To measure the instantaneous speed, what should be used? Select one O Two photogates only. O One photogate + glider with double flag O One photogate + glider with single flag O Two photogates + glider with double flag O Two gliders only The average speed becomes a close approximation to the instantaneous speed when Select one O The distance between the two photogates is maximized O The distance between the two photogates is reduced O The air track surface is inclined None of the offered choices fits The triction is reduced

A train is traveling at 50 m/s and needs to come to a stop before it hits an empty car abandoned on the tracks. It can decelerate at a rate of 2 m/s² and only has 300 meters to stop. Will it stop in time?

A spacecraft starts from rest, and makes a journey to a destination 389000 km from its starting point. It does so by accelerating at a constant rate of 9.79 m/s^2 up to the midpoint of the journey, and then decelerates at the same constant rate of 9.79 m/s^2 for the second half of the journey, ending at rest. How long did the entire journey take?     11 hr 2 min     5 hr 31 min     3 hr 30 min     2 hr 29 min
