Question

A body of 5 kg is moving with a velocity of 20 m/s. If a force of 100N is applied on it for 10s in the same direction as its velocity, what will now be the velocity of the body

• A. 200 m/s
• B. 220 m/s
• C. 240 m/s
• D. 260 m/s

Answer 1

Answer: (B)

220 m/s

Answer 2

$v = u + at = u + \left( \frac{F}{m} \right)t = 20 + \left( \frac{100}{5} \right) \times 10 = 220\mspace{6mu} m/s$
