Answer:
8.87 m/s^2
Explanation:
Acceleration is change in velocity over a change in time
27 to 53 = 26 m/s change in velocity
26 m/s / 3 s = 8.87 m /s^2
Answer:
The answer is below
Explanation:
The equation for a linear line graph is given by:
y = mx + b, where y and x are variables, m is the slope of the graph and b is the y intercept (that is value of y when x is zero).
The slope (m) of a line passing through two points
is given by:

A) The first line passes through the point (0, 0) and (10, 60). It is represented as (time, velocity). Hence the slope is:

B) The second line passes through the point (10, 60) and (15, 60). Hence the slope is:

C) The third line passes through the point (15, 60) and (40, -40). Hence the slope is:

D) The third line passes through the point (40, -40) and (55, 0). Hence the slope is:
