When you are 20 m away from a stopped hummer it begins accelerating away from you at 3 m/s/s . With what constant velocity should you run to catch the hummer?
Vf ^2 = Vi ^2 + 2ad
d = Vi * t + 0.5at^2
Vf = Vi + at
The Attempt at a Solution
I really don't know how to approach the problem. Assuming that they are asking for the minimum velocity...
Distance for runner:
Velocity (time) - 20 meters
Distance for hummer:
= 3/2 (t^2)
To find the initial velocity you would set the two equations equal to each other, but ther is also the time variable?!
Can someone please guide me. Thank you...
