An object of mass 2kg is free falling being given an initial velocity of -10 m/s. its initial vertical position is 20 m.

a.) sketch v(t), y(t), and a(t) graphs for the motion.

b.) Find the time when the object reaches the ground.

c.) Find the velocity of the object at the impact

d.) Suppose that simultaneously another object is projected straight up with an initial velocity of 10 m/s. prove if the other project will pass the first.

You throw a ball vertically upward with an initial velocity of 10 m/s from a window located 20 m above the ground. Knowing that the acceleration of the ball is constant and equal to 9.81 m/s^2 downward (this makes for negative acceleration as upward motion is positive and downward motion is negative and gravity pulls downward), determine: (a) The acceleration at t = 2 s (b) The equation for velocity (Because you are looking for an equation for velocity, you...
