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.
ANSWER:
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 gravity, a= 20 m/ as in figure below,
To find distance using,
S = ut +
Where S is the vertical distance, u is the initial velocity, a is the acceleration and t is time taken.
