Afigure shows a vertically moving block on the end of a cord. the graph next to the figure gives the vertical velocity component vy as a function of time to. the block's mass is 5.00kg. what is the tension in the cord?

what type of charge does it have? negative

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s
