Question

Frictionless track as shown in figure. The bullet remains inside the block and the system proceeds towards the semicircular track of radius 0.2 m. Where will be the block strike the horizontal part after leaving the semicircular track?

Answer 1

if initial velocity of bullet was known, we apply momentum conservation between block and bullet as they move together later we will now know. combined velocity. when it completes semi circle depending on velocity we can calculate time for it reach bottom i.e 0.4m. once time is known horizontal distance can be found
