A block weighing 10 N travels down a smooth curved track AB joined to a rough horizontal surface (figure 8-E5). The rough surface has a friction coefficient of e20 with the block. If the block starts slipping on the track from a point 1'0 in above the horizontal surface,how far will it move on the rough surface ?

Q.

A block weighing 10 N travels down a smooth curved track AB joined to a rough horizontal surface (figure). The rough surface has a friction coefficient of 0.20 with the block. If the block starts slipping on the track from a point 1.0 m above the horizontal surface, how far will it move on the rough surface?

Q. A block weighing 10 N travels down a smooth curved track AB joined to a rough horizontal surface as shown in figure below. The rough surface has a friction coefficient of 0.20 with the block. If the block starts slipping on the track from a point 1.0 m above the horizontal surface, how far will it move on the rough surface? (Assume g = 10 m/sec${}^2$)

Q. A block is released from rest from a height $h=5\text{m}$. After travelling through the smooth curved surface, it moves on the rough horizontal surface through a length $l=8\text{m}$ and climbs onto the other smooth curved surface through a height $h^{{}^{\prime }}$. If coefficient of friction of the rough surface is $\mu =0.5$, find $h^{{}^{\prime }}$.

Q. A block kept on a rough surface starts sliding when the inclination of the surface is '$\theta$' with respect to the horizontal. The coefficient of static friction between the block and the surface is:

Q. A small block is projected with a speed $v_0$ on a horizontal track placed on a sufficiently rough surface which turns into a semi-circle (vertical) of radius $R$. Find the main value of $V_o$ os that the body will hit the point A after leaving the track at its highest point. The arrangement is shown in the figure, given that the straight part is rough and the curved path is smooth. The coefficient of friction is $\mu$
