The second equation of motion of a uniformly accelerated ball along a straight line is stated ass = vft +1/2 at2The dimension of this equation is
Correct answer: D. [L][T-2]
- A. [L]
- B. [T]
- C. [L][T-1]
- D. [L][T-2]
Explanation
The second equation of motion is s = vft + 1/2 at2. The dimension of the first term vft is [L][T-1][T] = [L]. The dimension of the second term 1/2 at2 is [L][T-2][T2] = [L]. Since both terms have the same dimensions, the overall dimension of the equation is [L]. Option D is therefore the correct answer. Options A, B, and C are incorrect as they do not represent the dimensional analysis of the entire equation.
