A) V=35.3 mph, angle=31 deg g=gravity, u=coefficient of friction, r=radius, m=mass (which will be cancelled out later) N=m(v^2/r) uN=mg u(m(v^2/r)=mg You will get a formula of √rg/n for velocity v=√50(32.2)/0.6 v=51.8 ft/s or 35.3 mph

For the angle.. the formula of coefficient of friction is tan θ=f θ=tan^-1(0.60) θ=30.96º >>degree of friction the formula to use for the angle from the horizontal is tan(θ(horizontal)-θ(friction))=v²/gr input the values and you will get θ=329.034485º...
