Time of Flight, Maximum Height & Range

A boy can throw a stone up to a maximum height of 10 m. The maximum horizontal distance that the boy can throw the same stone up to will be

Show answer and solution

Answer: (d)

  1. Maximum height (vertical throw): u22g=10 m\frac{u^2}{2g} = 10\text{ m}
  2. Rmax=u2g=2×10=20 mR_{max} = \frac{u^2}{g} = 2 \times 10 = 20\text{ m}
  3. So the answer is (d) 20 m.
