Unformatted text preview: 4 rad/s and its moment of inertia is 125 kg∙m2. A 40.0-kg person climbs onto the carousel near its outer edge. What is the angular speed of the carousel after the person climbs aboard? [A] 1.41 rad/s [B] 1.57 rad/s Angular momentum is conserved, so [C] 1.83 rad/s [D] 2.26 rad/s with and Then (f) [4pt] A plane flies at a velocity of 70 m/s relative to the ground, in a direction 35o east of north. The wind blows toward the north at 50 m/s. What is the plane’s air speed (relative to the wind)? [A] 20 m/s [B] 41 m/s The desired speed is the magnitude Then [C] 99 m/s plane wind 35o [D] 120 m/s in the figure. Addition of velocities gives with You may recognize this as the Law of Cosines for the triangle formed by the three vectors. Then 10 (g) [4pt] A block with mass is being pushed by a constant force that makes an angle of with the horizontal as shown. The block is moving with constant velocity on a level surface. The coefficient of kinetic friction between the block and the surface is . Which on...
