Show that the component of the log’s weight down the slope is $1070\,\text{N}$.
The log begins at rest. A constant frictional force of $525\,\text{N}$ acts on it. It accelerates up the slope at $0.130\,\text{m s}^{-2}$.
Calculate the cable tension.
The log starts from rest at point $S$. It is hauled a distance of $10.0\,\text{m}$ to point $P$. Calculate, for the log, how long it takes to travel from $S$ to $P$.
Calculate, for the log, the magnitude of its velocity at $P$.
When the cable breaks as the log arrives at point $P$, sketch on Fig. 2.2 how the velocity $v$ varies with time $t$ for the log. The graph is to show $v$ from the start at $S$ until the log gets back to $S$.
Calculate, for the log, how long it takes to move from S to P.
Calculate, for the log, the magnitude of the velocity at P.
