A dragster and a driver together have mass of 942.2 kg. the dragster starting from rest attains a speed of 25.5m/s in 0.56 s.
1. find the average acceleration of the dragster during this time interval? I really need the formula
2. What horizontal force does the seat exert on the driver? i have the weight of the driver again i need the formula please

  • Physics -

    1. acceleration is speed change divided by time. In this case it is
    a = 25.5/0.56 m/s^2

    2. F = m a
    where m is the driver's mass (not weight)

    The answer, if you do it right, will be in newtons.
