A block. initially at rest , slides down a slope as shown. the frictional force is calculated to be 160N and the air resistance is 0.5v, where v is the velocity of the block. if the weight acting down the slope (parallel to the slope surface) is 250N, a)use Newton's 2nd law (f=ma) to derive an expression for the resultant force on the block b) rewrite the expression including the mass of the object and the acceleration term in the form dv/dt. c)find the particular solution if the velocity at the start of the slide is (t=0) is zero
