Chapter 1.2, Problem 11P

(a)

To determine

To show: The equation of motion can be written as $\frac{dv}{dt}=\frac{{\left(49\right)}^2-v^2}{245}$.

(b)

To determine

The expression for $v\left(t\right)$ at any time if $v\left(0\right)=0$.

(c)

To determine

To draw: The solution from part(b) by using the given data.

(d)

To determine

The effect of a quadratic drag force with that of a linear drag force by comparing with part (c).

(e)

To determine

The distance $x\left(t\right)$.

(f)

To determine

The time T taken by the object to fall 300 m.
