Tardigrade Admin · Accepted Answer

Total change in momentum =∫ F . d t= Area under F t curve. Area above t-axis will be positive and below t-axis will be negative in option (3) Area =-[(1/2) × 5 × 1]+(1/2) × 5 × 1=0

Q. In which of the following graphs, the total change in momentum is zero?

Total change in momentum $= \int F . d t =$ Area under $Ft$ curve.
Area above $t$ -axis will be positive and below $t$ -axis will be negative in option (3)
Area $= - [\frac{1}{2} \times 5 \times 1] + \frac{1}{2} \times 5 \times 1 = 0$

Q. In which of the following graphs, the total change in momentum is zero?

Total change in momentum =∫F.dt= Area under Ft curve. Area above t-axis will be positive and below t-axis will be negative in option (3) Area =−[21​×5×1]+21​×5×1=0
