I'm sure some of you will have a good laugh about this problem but its driving me bonkers! here goes: chameleons catch insects by rapidly extending their tongues. A chameleon's tongue accelerates at 250(m/s^2) for 20 ms (milliseconds i presume) then travels at constant speed for another 30 ms. during the total time 1/20 seconds how far does the tongue reach? this was all the information given for the problem. I have used kinematic equations before in my class but the professor moves from subject to subject without segue. During some point I'm sure he addressed problems like this but i just don't know what to do or how to start. any takers?
