A block of mass 8.9 kg is suspended from a pulley via a light cord. The pulley has a mass of 6.8 kg and a radius of 19 cm. Treat the pulley as a disk. If the
block is initially at a height of 2 meters above the ground, how long does it
take to reach the floor?
Report your answer to three decimal places.

scorpions are,

c.arachnids

  scorpions are animals in the order scorpiones, under the class arachnida, which makes them a distant cousin of spiders

happy to

pls mark as brainliest.

i think the answer is a, hope this is right, that would be my best guess.

the answer is a)

mark brainliest

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
