**Physics Problem:****Scenario:**At the top of a cliff 49 meters high, Raoul throws a rock upward with a velocity of 27 meters per second. **Question:**How much later should he drop a second rock from rest so that both rocks arrive simultaneously at the bottom of the cliff?**Solution Approach:**To solve this, apply the equations of motion to both rocks and find the time delay needed for the second rock.- **Rock 1** (thrown upwards): Use the equations of motion to determine the time taken for it to reach the bottom.- **Rock 2** (dropped from rest): Determine when to release this rock by accounting for the time taken by Rock 1. **Note:**This problem involves calculating the time taken by each rock using concepts of kinematics, such as projectile motion and free fall.

height, y = 49 m velocity, u = 27 m/s Now puting these values in equation of motion:
