On top of a tower (10 m from the ground), an object is launched straight up with an initial velocity. The object continues its flight in free fall to a maximum height
of 0.04 kilometer from top of the tower. After reaching the maximum height, the
object falls back to the ground,
A (3 pts) What is initial velocity of the object (on top of the tower at the height of 10
m)
B (3 pts) What is the velocity of the object just before it hits the ground?
c (3 pts) What is the total duration of the object's flight?
D (6 pts) Draw a position time, velocity-time, and acceleration-time graph to show
the motion of the object

Which quantities are scalars? choose all that apply a. distance b. speed c. acceleration d. velocity

If we relied solely on the nonrenewable resources found in the u. s., which one would we run out of first at current usage levels? a. natural gas b. oil c. uranium d. coal
