Marten throws a football from a balcony with a velocity of 14 m/s [E] to Kevin who is located 10 m [E] of Marten and 8 m below. Kevin plans to run forward (in the direction of east) at a constant velocity and catch the football. With what velocity should Kevin run in order to make the catch? Assume Kevin catches the football from 8 m below.

The electronic structure or chlorine is 2.8.7 what is the electronic structure of fluorine?

Aparticle's position is given by x = 3.00 - 9.00t + 3t2, in which x is in meters and t is in seconds. (a) what is its velocity at t = 1 s? (b) is it moving in the positive or negative direction of x just then? (c) what is its speed just then? (d) is the speed increasing or decreasing just then? (try answering the next two questions without further calculation.) (e) is there ever an instant when the velocity is zero? if so, give the time t; if not, answer "0". (f) is there a time after t = 3 s when the particle is moving in the negative direction of x? if so, give the time t; if not, answer "0".
