Problem 22PC

These are “plug-in-the-number” type activities to familiarize yon with the equations that link the concepts of physics. They are mainly one-step substitutions and are less challenging than the Problem. ? On a distant planet a freely falling object has an acceleration of 20 m/s2. Calculate the vertical distance an object dropped from rest on this planet covers in 1.5 s.

Step-by-Step Solution:

Solution Step 1 of 2 This problem can be solved using the equation of kinematics, since the object is dropped from height or vertical distance(S); its initial velocity will be zero,u=0. Under the acceleration due to 2 gravity, a= 20 m/s as in figure below, To find distance using, S = ut + at 2 2 Where S is the vertical distance, u is the initial velocity, a is the acceleration and t is time taken.
