05 kg chunk of ice is sliding at 14.0 m/s on the floor ice-covered valley when it collides with and sticks to her 5.05 kg chunk of ice that is initially at rest. (See ure 1).) Since the valley is icy, there is no friction. the collision, the blocks slide partially up a hillside then slide back down. e m m 1 of 1 Part A How fast are they moving when they reach the v Express your answer in meters per second. ▸ View Available Hint(s) 15 ΑΣΦ Submit Provide Feedback

9. A sliding gate 2 m wide and 1.5 m high lies in a vertical plane and has a co-efficient of friction of U.2 between itself and guides. If the gate weighs one tonne, find the vertical force required to raise the gate if [Ans. 377685 N] An immiscible liquid of sp. gr. 0.8 is filled on its upper edge is at a depth of 4 m from free surface of water.

Two large fixed parallel planes are 240 mm apart. The space between the surfaces is filled with oil of viscosity 0.81 N.s/m2. A flat thin plate 0.5 meter square area moves through the oil at a velocity of 0.3 m/s. calculate the drag force: A] When the plate is equidistant from both the planes, and B] When the thin plate is at a distance of 80 mm from one of the plane surface.

A Jet of oil of relative density 0.8 and of area 0.01 m² strikes normally on a stationary plate at a velocity of 20 m/s. Find the force exerted on the plate.
