For n>1. But I Still struggle to get further..

Homework Statement Prove; n^2 > n+1 for n = 2,3,4 by Induction Homework Equations The Attempt at a Solution p(n)= P(2) 2^2> 2+1 --> 4>3 Induction step: P(n+1): (n+1)^2 > (n+1) +1 (n+1)^2> n+2 n^2 + 2n + 1 > n+2 | -n n^2 +n + 1> 2 | -1 n^2 +n > 1 Is this correct, and how...

Average velocity is the rate of change of displacement with time. Δr=50m v=Δr/Δt Average velocity for the boy v=(2*Δr)/Δt For the student So the students average velocity. is twice the boys. So how do I show when they have the same rate? And Î`m missing the time to complete the task?

Homework Statement A guy and a student are competing against each other in a 100m long race. The guy start before the student. When the guy is halfway the student start running. They are finishing at the same time. We assume that at any time we can talk about their speed. Show that you and the...
