Marbles are exiting a container through a horizontal nozzle positioned 1.3 m above sandy ground. You notice that all the marbles land between 0.23 m and 0.41 m from the point directly below the end of the nozzle. What is the minimum initial speed of the marbles?

The minimum initial speed of the marbles are 2.6 m/s

Explanation:

Given that,

Height = 1.3 m

For vertical displacement,

We need to calculate the time

Using equation of motion

Put the value into the formula

We need to calculate the minimum initial speed of the marbles

Using formula of speed

Put the value into the formula

Hence, The minimum initial speed of the marbles are 2.6 m/s

like many students at university, you may be unhappy about the results you attain in exams. you may feel that even with all you are doing there must be something more -- or different-- you could be doing to get better grades. we have all at some time or other heard of that student who only studies a couple of hours for final exams and scores a's every time. we stand in awe of those who seem to breeze through without undue effort and seem to need very little in the way of studying to nail an exam. the reasons for success, in what i think are the vast majority of cases, are less esoteric than many students think: successful students consistently apply a series of productive strategies with view to attaining clearly identified learning and grade goals throughout the academic term.
