Question

The force acting on a body is (i + 4j + 6k) N in a time of 6s. The change in momentum of the

body is (kg ms–1)​

Answer 1

Answer:

43.6 kg ms-1

Explanation:

According to Newton,

Force * time = Change in momentum (dP)

Therefore

(i + 4j + 6k)* 6 = dP

6i + 24j + 36k = dP

|dP| = √6² + 24² + 36²

= √36 + 576 + 1296

=√1908

= 43.6 kg ms-1
