SUMMARY

The discussion centers on calculating the height of a cliff from which an object is dropped, taking 1.80 seconds to reach the water below. The key equation used is derived from the physics of free fall, specifically the formula for distance: \( d = v_0 t + \frac{1}{2} a t^2 \). Given that the initial velocity \( v_0 \) is 0 and the acceleration \( a \) is approximately 9.81 m/s², the height can be calculated as \( d = \frac{1}{2} \times 9.81 \times (1.80)^2 \), resulting in a height of approximately 15.87 meters.

PREREQUISITES
  • Understanding of basic kinematics
  • Familiarity with the equations of motion
  • Knowledge of gravitational acceleration (9.81 m/s²)
  • Ability to perform basic algebraic calculations
NEXT STEPS
  • Study the equations of motion in physics
  • Learn about free fall and gravitational acceleration
  • Explore real-world applications of kinematics
  • Practice solving problems involving projectile motion
USEFUL FOR

Students in physics, educators teaching kinematics, and anyone interested in understanding the principles of motion and free fall calculations.

An object dropped from the top of a cliff takes 1.80 s to hit the water below. What is the height of the cliff?



I do not know of any equation that would work as only one piece of information has been given



I could not even begin my calculations as I lacked information. Is it possible to solve this question?

You know the time, you know the acceleration (free fall), you know the initial velocity ("dropped" means vo=0). You can find the distance traveled.
 
Thanks!
