I get 8.8 m/s as my answer...don't know where I am wrong. Please help!

4. Base your answer to the following question on the picturebelow, which represents a plane 10 min length with acoefficient of kinetic friction of 0.2, inclined at an angle of53°. A block of weight 30 N is placed at the top of the plane and allowed to slide down. /.‘ 6m—| The velocity of the block after its 10 m slide down theplane is most nearly 1) 8.2 m/s2) 8.6 m/s3) 8.9 m/s4) 9.7 m/s 5) 10.0 m/s
