Homework Help: Equations of motion

    A car with an initial velocity of 60m/s slows down with deceleration of -8m/s^2. How far will it have travelled after 10 seconds?

    Hi failwhale, welcome to PF.

    Can you write down the relevant kinematic equations?

    S = u.t + 1/2. a. t^2

    substitute the value and find the answer, okay.

    One more thing. either use word "deceleration" or use minus sign. don't use it together otherwise it is acceleration.
