A person is pushing a wooden crate of mass \( m_0 = 20 \, \text{kg} \) at a constant speed \( v_0 = 1.2 \, \text{m/s} \) for \( \Delta x = 3 \, \text{m} \) along a rough horizontal floor that has a coefficient of friction \( \mu_k = 0.4 \). **Question 4:**If the person *continues* to push with about 80 N of force as before while the crate moves onto a different surface with a coefficient of friction \( \mu_k = 0.42 \), how does the motion of the crate change?

A mass m = 12 kg is pulled along a horizontal floor with NO friction for a distance d =6.6 m. Then the mass is pulled up an incline that makes an angle θ = 26° with the horizontal and has a coefficient of kinetic friction μk = 0.45. The entire time the massless rope used to pull the block is pulled parallel to the incline at an angle of θ = 26° (thus on the incline it is parallel to the surface) and has a tension T =49 N. With work and conservation of energy, how far up the incline does the block travel before coming to rest? (Measured along the incline.)
