A body moving with uniform acceleration has a velocity of -11 cm/s when its x coordinate is 3.00 cm. If itsx coordinate 2 s later is -5 cm, what is the magnitude in cm/square of its acceleration?

Distance travelled, s=-5-(+3)= -8 cm Initial velocity, u=-11 cm/s time, t=2 s
We use,
Therefore magnitude of acceleration in cm/s2 is 7.
