A box of mass m with an initial velocity of vo slides down a plane , inclined at theta with respect to the horizontal . The coefficient of kinetic friction is mu . The box stops after sliding a distance x . How far does the box slide ?

a) X = v0 squared /g (mu Sin theta -2 Cos theta)

b) X = v0 squared / 2g( mu Cos theta + Sin theta )

c) X = v0 squared /2g sin theta

d) X = v0 squared/g (mu Sin theta + Cos theta )

e) X = v0 squred/2g (mu Sin theta – Cos theta )

f) X = v0 squared /2g (mu Cos theta – Sin theta )

g) X = v0 squared/2g (Sin theta- mu Cos theta)

h) X = v0 squared/2g (mu Sin theta + Cos theta )

i) X = v0 squared / g ( Sin theta – mu Cos theta )

j) X = v0 squred / 2g mu Cos theta
