A 15 g ball is shot on a level ground from a spring gun whose spring has a force constant of 600N/m. The spring is compressed by 5 cm. The greatest possible horizontal range of the ball for this compression is :-

Options:

Answer:

Solution:

$\frac{1}{2} k x^{2} = \frac{1}{2} m v^{2}$ , so $v = 0.05 \frac{600}{0.015} = 10 m / s$

$R_{ma x} = \frac{v ^{2}}{g} = \frac{100}{10} = 10 m$
