Question

The chart shows data for four moving objects.

Answer 1

Answer:

Object Y has the greatest acceleration.

Step-by-step explanation:

We know that acceleration (a) = $\frac{(final\ velocity) - (initial\ velocity)}{time}$.

Lets calculate the velocity of each objects separately.

Acceleration of W (a) = $\frac{(final\ velocity) - (initial\ velocity)}{time}=\frac{(29-11)}{6} =3\ m\ s^-2$

Acceleration of X (a) = $\frac{(final\ velocity) - (initial\ velocity)}{time}=\frac{(34-10)}{12} =2\ m\ s^-2$

Acceleration of Y (a) = $\frac{(final\ velocity) - (initial\ velocity)}{time}=\frac{(40-12)}{7} =4\ m\ s^-2$

Acceleration of Z (a) = $\frac{(final\ velocity) - (initial\ velocity)}{time}=\frac{(28-20)}{8} =1\ m\ s^-2$

Comparing all the values we see that acceleration of object $Y$ is greatest among all.
