Question

A shell is fired from the bottom of a hill of slope 30°, with the barrel at 60° to the horizontal, at 14 $m / s$ . The distance along the slope to the point where the shell falls is about: (Take $g = 9.8 m / s^{2}$ )

Answer:

13.30

Solution:

$L = \frac{2 \times 196 \times 0.5 \times 0.5}{9.8 \times 0.75} = \frac{98}{7.35} = 13.3 m$ .

TestHub · Accepted Answer

L = 9.8 × 0.75 2 × 196 × 0.5 × 0.5 ​ = 7.35 98 ​ = 13.3 m .
