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?

mo = 20 kg vo = 1.2 m/s ∆x = 3 m μk = 0.4

A mass M = 12.0 kg is pulled up an incline plane by a F = 170 N. The plane angle is 30o with respect to the horizontal. The kinetic coefficient of friction between the surfaces is μ = 0.40. Calculate the acceleration of the block
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.)

Many birds can attain very high speeds when diving. Using radar, scientists measured the altitude of a barn swallow in a vertical dive; it dropped 208 m in 3.0 s. The mass of the swallow was estimated to be 0.018 kg, and its cross-section area as 5.6 x 10-4 m2. What was the drag coefficient for this swallow as it dove?
