The discussion revolves around calculating the time a bomb is in the air when dropped from a height of 2000 meters by a plane flying at a speed of 720 km/h. The problem involves concepts from kinematics, particularly focusing on the independence of vertical and horizontal motion.
Some participants have provided insights into the independence of vertical and horizontal components of motion, while others are clarifying the correct approach to the problem. There is an ongoing exploration of the initial conditions necessary for the calculations.
Participants are navigating the implications of using the correct initial vertical velocity and the assumptions surrounding the motion of the bomb. The discussion reflects a mix of interpretations regarding the relationship between horizontal speed and vertical fall time.
This is the correct equation to use, but not the correct initial velocity. All you care about is the vertical motion (which, as vincentchan points out, has nothing to do with the horizontal speed of the plane), so what's the initial speed in the vertical direction?hype_chicky said:So Viinitial is 720 km/h and d is 2000 m , g is 9.8 and to solve for t would i use the formuladeltay = Videltat + 1/2adeltay t^2?
