n boat starts from rest and accelerates at a constant rate to a final speed of 28 m/s over a distance of 780 m. How much time will this take?
Answered by bobpursley
Vf^2=Vi^2+2ad

solve for a, then..
28=at solve for t.

actually, there is an easier way. Avg velocity is 14m/s

time to travel= distance/avgvelocity
