In a game of shuffleboard (played on a horizontal surface), a puck is given an initial speed of 6.00 m/s. it slides a distance of 9.00 m before coming to rest. what is the coefficient of kinetic friction between the puck and the surface? write the answer with 2 decimal places

  about 0.20

Step-by-step explanation:

The speed, acceleration, and distance satisfy the equation ...

  v² = 2ad

So the acceleration is ...

  a = v²/(2d) = (6 m/s)²/(2×9 m) = 2 m/s²

If we take the acceleration due to gravity to be 9.8 m/s², the coefficient of kinetic friction is the ratio of these:

  k = (2 m/s²)/(9.8 m/s²) ≈ 0.20

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.
