An ice cart of mass 60 kg rests on a horizontal snow patch with coefficient of static friction `(1)/(3).` Assuming that there is no vertical acceleration, find the magnitude of the maximum horizontal force required to move the ice cart.`(g = 9.8 ms ^(-2))`

Options

A. A)100 N
B. B)110 N
C. C)209 N
D. D) 196 N

Answer

D

Explanation

Force applies against friction
`f _(k) = mu _(k) R = mu _(k) mg = (1)/(3) xx 60 xx 9.8 = 196 N`
