Exam-style question
Try this first
In a free fall experiment, a ball takes 2 seconds to hit the ground from rest. Calculate the height from which it was dropped using the formula h = 0.5 * g * t². Use g = 9.81 m/s².
Model answer
What a good answer should say
- The height from which the ball was dropped is 19.62 meters.
Explanation
Why this works
This question assesses the ability to apply the kinematic equation for free fall. By substituting the known values of g and t into the formula, students can find the height accurately, demonstrating their understanding of motion under gravity.
