A stone is thrown horizontally from the top of a building. It has an initial speed of 5m/s2. Use g= 10m/s2. The height of the building is 50m. The ground is at the base of the building. a) Define your initial conditions at t=0 in the following:
xi= yi= (Vx)i= (Vy)i=

b) Find the time the stone stays in the air

c) find the range (Xf-Xi) of the stone:

d) find the speed of the stone at the landing

Which of the following is not a part of the respiratory system? a. pharynx b. trachea c. pancreas d. larynx

What is a costume plot? why is it important to a film or theater production?

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".
