1. The ball on top of the table rolled horizontally as Juan hit it while playing. After 6 seconds, it reached the floor. How high was the table where the ball came from?
Answer (1)
Answer:The table from which the ball originated was 176.4 meters high.For vertical motion, apply the kinematic equation below:Δy = voyt + (1/2)gt²Given:Initial vertical velocity (voy): 0 m/s.Acceleration due to gravity (g): 9.8 m/s² (due to gravity).Time of fall (t): 6 seconds Vertical displacement (Δy): ?Let's enter the values now:Δy = (0 m/s)(6 s) + (1/2)(9.8 m/s²)(6 s)²Δy = 0 + (1/2)(9.8 m/s²)(36 s²)Δy = 0 + (4.9 m/s²)(36 s²)Δy = 176.4 meters
