Question

A shell is shot with an initial velocity of 20 m/s, at an angle of a = 60° with the horizontal. At the top of the trajectory, the shell explodes into two fragments of equal mass. One fragment, whose speed immediately after the explosion is zero, falls vertically. Find the velocity of the second fragment. How far from the gun does the other fragment land, assuming that air drag is negligible?

Step 1

Step 1: Calculate the horizontal velocity component of the shell: Given initial velocity = 20 m/s, angle = 60° Horizontal velocity component = 20 * cos(60°) = 10 m/s Show more…
