Question

0. A body of mass 6 kg is acted on by a force so that its velocity changes from 3 ms -1 to 5 ms -1 , then change in momentum is
(a) 48 N-s (b) 24 N-s
(c) 30 N-s (d) 12 N-s

Answer 1

Explanation:

12N/s..

______________________

Answer 2

Answer:

$change \: in \: momentum = m(v - u) \\ \\ = 6 \times (5 - 3) \\ \\ = 6 \times 2 \\ \\ = 12 \: newton \: seconds.$

Explanation:

CHANGE IN MOMENTUM = 12 NS.

OPTION (D) IS CORRECT.
