Given Information:

• Neglect air resistance.
• The magnitude of the acceleration is 9.80 m/s².
• The eventual position of the ball is at the base of the building, 50.0 m below this initial position.
• Upward is defined as positive. Displacements, velocities, and accelerations directed upwards are positive. Conversely, if directed downwards, these same quantities are negative. Thus, the base of the building is located at -50.0 m, and acceleration is -9.80 m/s².
• Building is 50.0 m tall

Questions to Answer: Near the edge of the building the ball is thrown downward with an initial velocity of -10.0 m/s, at time t = 0.00 s

• How long does the ball take to reach the base of the building?
• What is the final velocity of the ball just before striking the ground?
