Problem

The magnitude of the average velocity of a particle in projectile motion between its starting point and the highest point of its trajectory is, where the projection speed is uu and the angle of projection from the horizontal is θ\theta: (1) ucos⁡θu\cos\theta (2) u21+3cos⁡2θ\frac{u}{2}\sqrt{1+3\cos^2\theta} (3) u22+cos⁡2θ\frac{u}{2}\sqrt{2+\cos^2\theta} (4) u21+cos⁡2θ\frac{u}{2}\sqrt{1+\cos^2\theta}
