Question

Projectile Motion


1. A projectile is launched at ground level with an initial speed of 50 0 m/s at an angle of 30.0

Answer 1

All quantities that can be asked to found in such tasks can be calculated using these formulas:

Let $u = 50m/s$ be the initial speed and $\theta =30\degree$ the launch angle. Then, for example, the range of the motion is given as follows:

$$R = \dfrac{u^2\cdot \sin2\theta }{g} = \dfrac{50^2\cdot \sin(2\cdot 30\degree)}{9.81} \approx 221 m,$$
