Hi! I'm have difficulty with this question. If anyone can help it would be a lot of help.
Problem
Raj is late for the bus, and as he closes the door to his house, he notices the bus, located 25m away, has begun to accelerate away from him at 1.0 m/s2. Raj begins to chase the bus immediately at a speed of 3.4 m/s. Is Raj able to catch the bus? If he does, where does he catch up to it? If he does not, calculate Raj's frustration distance.
What I've tried to solve
dbus = draj
1/2(v)t2 = vt
1/2(1.0)t2 = 3.4t
0=-1/2t2 + 3.4 t
Used quadratic formula to get
t = -0.25 OR t = 7.08
But at 7.08s Raj is no where near the bus because it takes him 7.352 seconds to reach 25m the distance the bus was originally from Raj...
It doesn't make any sense!
Another question
What is frustration distance? and how can it be calculated?
