In a test run, a certain car accelerates uniformly from zero to 17 m/s in 2.95s.

a.) what is the magnitude of the car's acceleration?

b.) how long does it take the car to change it's speed from 8.5m/s to 17m/s?

c.) will doubling the time always double the change in speed?

  • physics -

    a=changevelociyt/time

    time=changevelocity/a

    velocity=vi+at no
