ASS kg running back travelling at 6.3 m/s moves toward a 95 kg linebacker running at 4.2 m/s Which athlete has more kinetic energy? 3. A 2.00 kg mass is attached to...
ron and judy each pull a 40 kg crate across a rough floor at constant speed for a distance of 2.0 m. ron pulls horizontally and judy pulls at an angle of 30 degrees above horizontal. the coefficient friction between each crate and the floor is 0.50. a.) calculate the work done by ron b.) calculate the work done by judy c.) is the work ron does on his crate, more, less, or the same as the work judy does...
A dad pulls his child on a sled at a constant speed across a rugged snowy road with a force of 159 N in a direction of 42° above the horizontal. The mass of the child and sled is 38 kg. Compute the coefficient of friction. (HINT: Set up the force equations and Derive the expression the coefficient of friction between sled and snow.)
A person pulls a block across a rough horizontal surface at a constant speed by applying a force F at a slight angle as shown. A free-body force diagram is drawn for the block. The arrows in the diagram correctly indicate the directions, but not necessarily the magnitudes of the various forces on the block A student states that F fk and Fv W (here W stands for weight, which we call Fc) since the velocity is constant and thus...
A horizontal force pulls a 40- kg bag of fertilizer across the floor. What is the minimum force required if the coefficient of friction is 0.37?
A mother pulls her child on a sled at a constant speed across a rugged snowy road with a force of 160 N in a direction of 45° above the horizontal. The mass of the child and sled is 41 kg. What is the coefficient of friction. Write out all steps and explain.
