Anyone can help?? I need it done before 9am please!!

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:

the average speed is 24.57 km/hr

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
