Answer:

Final velocity, V = 11.5m/s

Explanation:

Given the following data;

Initial velocity, U = 2.5m/s

Acceleration, a = 1.5m/s²

Time, t = 6secs

To find the final velocity, we would use the first equation of motion

V = U + at

Substituting into the equation, we have

V = 2.5 + 1.5*6

V = 2.5 + 9

Final velocity, V = 11.5m/s

1) The average velocity is 56 m/min

2) The average velocity is -83 m/min

Explanation:

The average velocity of an object is given by

$v=\frac{d}{t}$

where

d is the displacement (change in position)

t is the time elapsed

In the graph in the problem, the displacement corresponds to the distance, therefore to the change in the y-variable ( $\Delta y$ ), while the time elapsed is the change in the x-variable ( $\Delta x$ ), so the average velocity can be written as

$v=\frac{\Delta y}{\Delta x}$

At point A, we have:

$y_A = 5 m\\x_A = 0.1 min$

At point B, we have:

$y_E = 55 m\\x_A = 1 min$

So, we have

$\Delta y= 55 -5 = 50 m\\\Delta x = 1.0-0.1 = 0.9 min$

So the average velocity is

$v=\frac{50 m}{0.9 min}=56 m/min$

In this part instead, we have the following:

At point F, we have:

$y_F = 55 m\\x_A = 1.3 min$

At point H, we have:

$y_H = 30 m\\x_A = 1.6 min$

So, we have

$\Delta y= 30 -55 = -25 m\\\Delta x = 1.6-1.3 = 0.3 min$

So the average velocity is

$v=\frac{-25 m}{0.3 min}=-83 m/min$
