What is the angle of projection if, at maximum height, the angle with the horizontal is $\tan^{-1}2$?

The angle of projection $\theta$ is $\tan^{-1}4$. This is derived by relating the range $R$ and maximum height $h$ using the condition that at maximum height, $\tan(\tan^{-1}2) = \frac{h}{R/2} = 2$, which simplifies to $R=h$.

How is work done by a variable force $F(x)$ calculated from an initial position $x_1$ to a final position $x_2$?

Work done by a variable force is calculated by integrating the force function with respect to displacement over the given limits: $W = \int_{x_1}^{x_2} F(x) dx$. This method sums the infinitesimal work done at each point.
