A force of 10 newton acts on a body of mass 20 kg for 10 seconds. Change in its momentum is
Options
(a) 5 kg. ms⁻¹
(b) 200 kg. ms⁻¹
(c) 100 kg. ms⁻¹
(d) 1000 kg. ms⁻¹
Correct Answer:
100 kg. ms⁻¹
Explanation:
Given: Force = 10 and time = 10
Change in momentum = Impulse = Force × time
= 10 × 10 = 100 kg. ms⁻¹
