Homework Help: A dragsters acceleration

  1. Oct 15, 2006 #1
    A dragser and a driver together have a mass 905.5 the dragster, starting at rest, attains a speed of 25 m/s in .61s. find the average acceleration of the dragster during the time interval. answer in units of m/s.

    ok im assuming we have 3 variable for a kinematic equation t=.61s, v.=0, and v=25m/s so i would solve for acceleration using v=v.+at ....... right? If not I need some help please.

    v=v.+at is correct, as is t=.61s, v.=0, and v=25m/s, which gives . . .

    See the definition of acceleration here -

    Use the link "Motion equations when acceleration is constant" to see equations for 'constant' acceleration.
