Expert Solution

Answer to Problem 41E

  t=v°±v°2+2ghg

Explanation of Solution

Given information:

  h=12gt2+v°t

Formula used:

  • Transposition of terms.
  • For ax2+bx+c=0

    x=b±b24ac2a

Calculation:

  h=12gt2+v°t12gt2+v°th=0

Using quadratic formula to find the value of u

  t=b±b24ac2at=v°±v°24(g2)(h)2(g2)t=v°±v°2+2ghg
