Question

When 1 N force acts on 1 kg body that is able to move freely, the body receives

• A. A speed of 1 m/sec
• B. An acceleration of $1m/\sec^{2}{}$
• C. An acceleration of $980cm/\sec^{2}{}$
• D. An acceleration of $1cm/\sec^{2}{}$

Answer 1

Answer: (B)

An acceleration of $1m/\sec^{2}{}$

Answer 2

$a = \frac{F}{m} = \frac{1\mspace{6mu} N}{1\mspace{6mu} kg} = 1\mspace{6mu} m/s^{2}$
