Please explain in detail and step by step a 1.0kg block is held at rest against a spring with a force constant k = 740N/m . Initially, the spring is compressed a distance d. When the block is released, it slides across a surface that is frictionless except for a rough patch of width 5.0cm that has a coefficient of kinetic friction = 0.40. Find d such that the block's speed after crossing the rough patch is 2.4m/s.
A beam of hydrogen molecules (H2) is directed toward a wall, at an angle of 50° with the normal to the wall. What is the beam's pressure on the wall
A thin flat plate is installed in a water tunnel as a splitter. The plate is 0.3 m long and 1 m wide. The free stream speed is 1.60 m/s. laminar boundary layers form on both sides of the plate. The boundary-layer velocity profile is approximated as p..
A 0.65kg block of ice is sliding by you on a very slippery floor at 3 m/s. As it goes by, you give it a kick vertical to its path. Your foot is in contact with the ice block for 0.003 seconds.
