Imagine the track in the Gizmo went on forever. If there were no friction, how long would it take the cart to stop after you turned off the fan? Explain.

Amass has an acceleration of 10- 2t. what is its velocity and displacement if it started at x- 4m and the initial velocity was 8m/s? at what time does it have 0 velocity? graph all graphs.

Athermometer is removed from a room where the temperature is 70° f and is taken outside, where the air temperature is 10° f. after one-half minute the thermometer reads 60° f. what is the reading of the thermometer at t = 1 min? (round your answer to two decimal places.) ° f how long will it take for the thermometer to reach 30° f? (round your answer to two decimal places.)

Using the work energy theorem. what is the velocity of a 850kg car after starting at rest when 13,000j of work is done to it.
