Question

please answer the following

Answer 1

Answer:

avg. velocity is 0.5m/s

Explanation:

we know

$average \: velocity = \frac{total \: displacement}{tota l \: time \: taken}$

• First we calculate displacement

By definition of displacement we can say that

Displacement = 2meters ( just join A and B the distance between them is displacement)

• Second we calculate time

given speed is 1 m/s and 4 steps are taken

so for each step it will take 1 second

so a total of 4 seconds are taken

• Lastly we got both values. just put the values in equation

$v = \frac{displacement}{time}$

$v = \frac{2}{4}$

$v = \frac{1}{2}$

$finally \: velocity = 0.5 \: \frac{m}{s}$
