37^\circ

. The coefficient of friction between the body and the plane varies as

\mu = 0.3x

, where

x

is the distance travelled down the plane by the body. The body will have maximum speed (1) At

x = 1.16\ \text{m}

(2) At

x = 2\ \text{m}

(3) At the bottommost point of the plane (4) At

x = 2.5\ \text{m}
