Question

3. On "The Simpsons," when Bart fires Mr. Burns as his father, Mr. Burns is dropped through his own trap door. When Mr. Smithers jumps after him, with what speed must he initially propel himself downward in order to reach the ground at the same time as Mr. Burns? Assume that Mr. Burns fell down the trap 2.5 seconds before Smithers jumped in and that the pit is 200-m deep (ignore air resistance)

please Up Vote. otherwise just comment down the problem/confusion/error I will get back to you asap.

According to the question- the person who jumped before will reach the ground in H=200m t = 24 seconds g = 9.81 m/s² and person who jumped later let say with - Velocity u should take 2.5 second less so by Newtons Equation- t = t - 2.5 f = ut +4.g. 42 200 = a ( -205) + 2 (18-25) to vote P1200 - 6.38 seronta 200 = U (3188) + 9181(15.1) + u: 12 5 73 m/A : 32 / 6 m/A | u 3.88
