Question

A force of 100 dynes acts on mass of 5 gm for 10 sec. The velocity produced is

• A. 2 cm/sec
• B. 20 cm/sec
• C. 200 cm/sec
• D. 2000 cm/sec

Answer 1

Answer: (C)

200 cm/sec

Answer 2

Acceleration $a = \frac{F}{m} = \frac{100}{5} = 20\mspace{6mu} cm/s^{2}$

Now $v = at = 20 \times 10 = 200cm/s$
