A box with a mass of 2 $\mathrm{kg}$ accelerates in a straight line from 4 $\mathrm{m} / \mathrm{s}$ to 8 $\mathrm{m} / \mathrm{s}$ due to the application of a force whose duration is 0.5 $\mathrm{s}$ . Find the average strength of this force.(A) 4 $\mathrm{N}$(B) 8 $\mathrm{N}$(C) 12 $\mathrm{N}$(D) 16 $\mathrm{N}$

Hi, everyone. Here it is. Given a box. Uh huh. Of mask two kg Accelerate from initial velocity of four m per second to final velocity of eight m per second in the time interval up 15 seconds. We have to calculate the average food supply Forces got the rate of change of momentum. Final momentum minus initial momentum upon time interval masses to eight minus four upon 40.5. So it is 1600. Mhm answered. It is correct.
