Question

The given figure shows a plot of the time dependent force F_x acting on a particle in motion along the x-axis. What is the total impulse delivered by this force to the particle from time t = 0 to t = 2second?

(A) 0 

(B) 1 kg-m/s 

(C) 2 kg-m/s 

(D) 3 kg-m/s

Answer 1

Correct option (C) 2 kg-m/s

Explanation:

Impulse = ∫Fdt

= Area under curve

= 1/2(2) (2) = 2kg-m/sec
