The chart shows data for four moving objects.Which object has the greatest acceleration?W XYZ
Accepted Solution
A:
Answer:Object Y has the greatest acceleration.Step-by-step explanation:We know that acceleration (a) = [tex]\frac{(final\ velocity) - (initial\ velocity)}{time}[/tex].Lets calculate the velocity of each objects separately.Acceleration of W (a) = [tex]\frac{(final\ velocity) - (initial\ velocity)}{time}=\frac{(29-11)}{6} =3\ m\ s^-2[/tex]Acceleration of X (a) = [tex]\frac{(final\ velocity) - (initial\ velocity)}{time}=\frac{(34-10)}{12} =2\ m\ s^-2[/tex]Acceleration of Y (a) = [tex]\frac{(final\ velocity) - (initial\ velocity)}{time}=\frac{(40-12)}{7} =4\ m\ s^-2[/tex]Acceleration of Z (a) = [tex]\frac{(final\ velocity) - (initial\ velocity)}{time}=\frac{(28-20)}{8} =1\ m\ s^-2[/tex]Comparing all the values we see that acceleration of object [tex]Y[/tex] is greatest among all.
