A square hockey table has a side length of s=1.52m. On the table, pucks slide across a horizontal table with effectively no friction. (Ignore friction). At the time t=0s a puck is launched with a speed of v1=0.300 m/s from the corner at an angle of 40.1 degrees with respect to the bottom edge of the table. At the same time, another puck is launched from an adjacent corner at an angle of 58.1 degrees at a speed that the pucks will collide. How long after the launch will the collision happen? Ignore the size of the pucks.
