A 15 g ball is shot from a spring gun whose spring has a force constant of 600 N/m. The spring is compressed by 5 cm. The greatest possible horizontal range of the ball for this compression is (g = 10 m/s 2 )
Text Solution
Verified by ExpertsThe correct answer is:
B
For getting horizontal range, there must be some inclination of spring with ground to project ball.
⇒ ⇒ 
…..(i)
But K.E. acquired by ball = P.E. of spring gun
…..(ii)
From equation (i) and (ii)
=10m.
