Answer to Question #246130 in Molecular Physics | Thermodynamics for Rod

Question

3. A rubber chicken is launched straight up at speed v from ground level. Find each of the following if the launch speed is tripled (in terms of any constants and v).
max height
hang time
impact speed

Answer 1

Solution.

$h_{max}=\dfrac{v^2}{2g};$

$h_{max}=\dfrac{9v^2}{2g};$

$t= 2\sdot \dfrac{v}{g};$

$t=2\sdot \dfrac{3v}{g};$

$v_{impact}=v;$

$v_{impact}=3v;$

Answer: $h_{max}=\dfrac{9v^2}{2g};$

$t=2\sdot \dfrac{3v}{g};$

$v_{impact}=3v;$
