Vertically projected body-velocity after 1nth\frac{1}{n}^{th} of its time of ascent(tat_{a})

we know that, v=u+at\boxed{v=u+at}

here, v=v'

u=u

a=-g

t=tan\frac{t_{a}}{n}

when, t=tat_{a}

v=o

a=-g

=>u-gtat_{a}=0

=>u=gtat_{a}__(1)

when, t=tan\frac{t_{a}}{n}

v'=u-gtan\frac{t{a}}{n}

v'=nugtan\frac{nu-gt_{a}}{n}

v'=nuun\frac{nu-u}{n} [since, from (1)]

v=un1n\boxed{v'=u\frac{n-1}{n}}

therefore, the velocity becomes n1n\frac{n-1}{n} times its projected velocity

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

  • Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
  • Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
  • Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
  • Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.
