Question

The value of acceleration due to gravity is 9.8 $m{s}^{-2}$. Its value in km $mi{n}^{-2}$ will be

• A. 35.3
• B. 58.3
• C. 5.9
• D. 17.6

Answer 1

The correct option is A

35.3

Acceleration [a] = [LT⁻²]

$\frac{1m{s}^{-2}}{1kmmi{n}^{-2}}=\frac{\frac{1m}{s^2}}{\frac{{10}^{3}m}{(60{)}^2}}$

$\therefore 9.8\times 3.6=35.28kmm{s}^{-2}$
