Question

Find how the total acceleration $\omega$ of the balloon depends on the height of ascent.

• A. $\omega =2a{v}_0$
• B. $\omega =-2a{v}_0$
• C. $\omega =a{v}_0$
• D. $\omega =-a{v}_0$

Answer 1

The correct option is C $\omega =a{v}_0$

Vertical direction:
Constant velocity so no acceleration.
Horizontal direction:
$v=ay$
$v=a\times v_{0}t$
$a=\frac{dv}{dt}$
$a=a{v}_0$
