Analysis Ask the learners to answer the activity titled: Drop Me Read and analyze the situation. A student drops a tennis ball from the tall building. The time it takes the ball to reach the ground for the three trials is found in Table 4. 2. Calculate the height covered by a tennis ball dropped from a tall building using the formula h = agt 2 2 (since vi = 0). Note: Height is negative when it is below the point of release. C. Abstraction Have the learners answer the guide question Q1. What is the velocity of the ball just before it hits the ground? Use the formula vf = agt since vi = 0. Try also calculating final velocity using the formula vf = √2agh and compare your answers. Use the average time and height. Q2. If the actual height of the building is 8.00 m, how will you compare it with average height in the table? D. Application Address: Brgy.
