An object travels a distance of 32 cm in 17.6 seconds from start to finish. If its acceleration is uniform and its initial velocity zero, then what are its average velocity, acceleration and final velocity?
Dv = ds/dt
@&
vAve = `ds / `dt.
`dv = vf - v0
*@
Vave = 32 cm / 17.6 s = 1.818 cm/s
a = the ave roc of V/dt
a= 3.636 cm/s / 17.6 s = 0.206 cm/s^2
final V = 3.636 cm/s
I drew a graph to help work this problem.
