Question

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

A

$2000cm/\sec$

B

$200cm/\sec$

C

$20cm/\sec$

D

$2cm/\sec$

Answer

$200cm/\sec$

Explanation

Solution

$v = u + at = 0 + \left( \frac{F}{m} \right)\mspace{6mu} t = \left( \frac{100}{5} \right) \times 10 = 200\mspace{6mu} cm/\sec$
