Ababy crawls from x=1.0m to x=4.25m at an average velocity of 0.226 m/s. how much time did it take? (unit=s)

From x = 1.0 m to x = 4.25 m, displacement = 3.25 m

Average velocity of crawling of baby =  0.226 m/s

We know that time taken = Displacement/Time

                                          =

                                           = 14.38 seconds

So, the baby will take a time of 14.38 seconds from x=1.0m to x=4.25m at an average velocity of 0.226 m/s.

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be
