A small block with a mass of 0.0900 kg is attached to a cord passing through a hole In a frictionless, horizontal surface. The block Is originally revolving at a distance of 0.40 m from the hole with a speed of 0.70m/s. The cord is then pulled from below, shortening the radlus of the circle in which the block revolves to 0.10 m. At this new distance, the speed of the block is observed to be 2.80 m/s. What is the tension In the cord In the final situation when the block has speed v-2.80m/s? Option1 Option2 Option3 Option4 Option5 7.1 N 0.11 N 6.5 N 0.12 N 2.11 N

Asmall block with a mass of 0.0900 kg is attached to a cord passing through a hole In a frictionless, horizontal
surface. The block Is originally revolving at a distance of 0.40 m from the hole witha speed of 0.70m/s. The
cord Is then pulled from below, shortening the radlus of the circle in which the block revolves to 0.10 m. At
this new distance, the speed of the block Is observed to be 2.80 m/s. What is the tension In the cord In the
final situation when the block has speed v-2.80m/s?
