Question

A body is projected with an initial velocity of (5 $\hat{i}$ + 8 $\hat{j}$) m/s. The range of the projectile (g = 10 m / $s^2$)

• A. 8 m
• B. 30 m
• C. 10 m
• D. 20 m

Answer 1

The correct option is A

8 m

The horizontal and vertical component of projection velocity are 5 m/s and 8 m/s respectively.

The horizontal range is given by,
R = $\frac{2u_x{u}_y}{g}$
