Three boxes, with masses m1, m2, m3 (kg) are stacked vertically; the bottom box is in contact with a rough floor and the surfaces between each box are also rough. An external force Fext (N) acts on the bottom box at an angle of XX degrees relative to the horizontal, as a result of which all three masses accelerate together with an acceleration a (m/s^2). a) Identify the number of forces acting on each box, b) starting with the top...

The figure below show three masses m1=1.1 kg, m2=2.8 kg, and
m3=4.3 kg which undergo two successive collisions. The first
collision between m1, which has an initial velocity v=8.2 m/s, and
m2 (which is initially at rest) is completely inelastic. The second
collision between the combined mass m1+m2 and m3 (which is
initially at rest) is elastic. What is the velocity of m3 after the
second collision?

Three carts of masses m1 = 3.50 kg, m2 = 8.00 kg, and m3 = 3.00 kg move on a frictionless, horizontal track with speeds of v1 = 7.00 m/s to the right, v2 = 3.00 m/s to the right, and v3 = 5.00 m/s to the left, as shown below. Velcro couplers make the carts stick together after colliding. (a) Find the final velocity of the train of three carts. Give me the magnitude in m/s.
