Vedclass · Answer

(B) Given: Mass $m = 50 \, g$,Initial velocity $v_0 = 20 \, cm/s$,Force $F = 50 \, dyne$,Time $\Delta t = 5 \, s$.The impulse-momentum theorem states that the change in momentum is equal to the impulse applied:$F \cdot \Delta t = \Delta p$$F \cdot \Delta t = p - p_0$$p = p_0 + F \cdot \Delta t$Since initial momentum $p_0 = m \cdot v_0$:$p = (50 \, g 	imes 20 \, cm/s) + (50 \, dyne 	imes 5 \, s)$$p = 1000 \, g \cdot cm/s + 250 \, g \cdot cm/s$$p = 1250 \, g \cdot cm/s$

$A$ body of mass $50 \, g$ has a velocity of $20 \, cm/s$. If a constant force of $50 \, dyne$ acts on it,what will be its momentum after $5 \, s$?
