Question
If initial velocity of an object is zero, then distance covered in time t and acceleration of 9.8 m/s² will be
Correct Answer
Option C is the correct answer.
Detailed Explanation
From s = ut + ½at², with u=0 and a=9.8 m/s², s = ½ × 9.8 × t² = 4.9 t².
Hint
Use the equation of motion for constant acceleration starting from rest.
