A) 10 m/s
B) \[\frac{mgR\sin \theta }{B{{l}^{4}}}\]
C) \[\Omega \]
D) None of these
Correct Answer: C
Solution :
As seen from the cart, the projectile moves vertically upward and comes back. The time taken by cart to cover 80 m \[11.4\Omega ,15.5A\] For a projectile going upward \[30.7\Omega ,6.5A\] and \[40.4\Omega ,5A\] \[50\Omega ,5A\] \[{{R}_{1}}\] \[{{R}_{2}}\] \[{{R}_{1}}>{{R}_{2}}\]
