Answer: the answer for this is 19 i.e option a
Explanation:
We have to integrate force with respect to time
Delta p = F.T
at integration
A part come t^4 + t^3 - t^2
Therefore [2^4-1^4] +[2^3-2^3] -[2^2-1^2]
By solving this you'll get 19

Answer:
Change in momentum of the particle is 19 kg-m/s
Explanation:
Given that,
Force acting on a particle varies with time is given by :
We need to find the change in momentum of the particle in interval t= 1 s to t = 2 s. According to second law of motion :
p = 19 kg-m/s
So, the change in momentum of the particle is 19 kg-m/s. Hence, this is the required solution.
