Until a train is a safe distance from the station it must travel at 5 m/s. once the train is on open track it can speed up
to 45 m/s. if it takes a train 8 seconds to reach 45 m/s, what is the acceleration of the train? (round your answer to
the nearest whole number)
o 4 m/s2
o 5 m/s2
o 6 m/s2
o 7 m/s2
intro

Acoyote chasing a rabbit is moving 8.00 m/s due east at one moment and 8.80 m/s due south 4.25 s later. let the x axis point due east and the y axis point due north. find the direction of the coyote's average acceleration during that time.

Abag of potato chips contains 2.00 l of air when it is sealed at sea level at a pressure of 1.00 atm and a temperature of 20.0 deg c. what will be the volume of the air in the bag if you take it with you, still sealed, to the mountains where the temperature is 7.00 deg c and atmospheric pressure is 70.0 kpa? assume that the bag behaves like a balloon and that the air in the bag is in thermal equilibrium with the outside air.

Which of the following is not an appropriate unit for acceleration? (kg/12 mihr? m/min/sec cm/30c?
