Question

A motorcyclist is coasting with the engine off at a steady speed of 24.5 m/s but enters a sandy stretch where the coefficient of kinetic friction is 0.70. Will the cyclist emerge from the muddy stretch without having to start the engine if the sand lasts for 12 m? no yes Submit Request Answer

Step 1

The force of kinetic friction is given by $F_k = \mu_k * N$, where $\mu_k$ is the coefficient of kinetic friction and N is the normal force. In this case, the normal force is equal to the weight of the motorcyclist, $N = mg$, where m is the mass of the Show more…
