Question

A projectile is thrown from a point in a horizontal place such that its horizontal and vertical velocity component are 9.8 m/s and 19.6 m/s respectively. Its horizontal range is

• A. 4.9 m
• B. 9.8 m
• C. 19.6 m
• D. 39.2 m

Answer 1

Answer: (D)

39.2 m

Answer 2

We know $R = \frac{2u_{x}u_{y}}{g} = \frac{2 \times 9.8 \times 19.6}{9.8}$ $= 39.2m$

Where $u_{x} =$horizontal component of initial velocity, $u_{y} =$vertical component of initial velocity.
