Please answer in more details and while using formula or some hypothesis, use the phrase according to and explain it very well in sentences.

1. A block of mass 3.0 kg is pulled up an incline by a string. In a one dimensional inertial reference frame with coordinate axis that runs up the incline the acceleration of the block is 10m and is constant. The tension in the string is measured to be 21 N and the normal force of the incline against the block is measured to be 24 N. What is the coefficient of kinetic friction between the block and the incline? 2. A block of mass 5.0 kg is on an incline that makes an angle of 12 with the horizontal. The coefficient of kinetic friction between the block and the incline is 0.10. A string pulls on the block. The string runs parallel to the incline, then over a (approximately frictionless and inertia free, so ignore these properties) wheel at the end of the incline, then down to a otherwise free hanging triangular object of mass 1.0 kg. (a) Construct an inertial reference frame to describe the position of the block. (b) What is the acceleration vector of the block
