Determine the position, velocity, acceleration, and distance traveled at t=8s?

The position of a particle that moves along the x-axis is given by x=(t^3)-3(t^2)-45t m

where t is the time in seconds.

    x(8)=512-3(64)-45(8)=-40 m

    Vel=3t^2-6t-45

    Vel(8)=3(64)-48-45=99 m/sec

    acc=6t-6

    acc(8)=48-6=42 m/sec^2

    distance=x(0)-x(8)=0-(-40)=40 meters

    God bless you.
