Consider the collision pictured below. While m2=10kg is initially at rest, horizontally moving m1=5kg with a speed of v1=14.9m/s collides with it. After the collision, the two masses scatter with speeds of v1′=8.3m/s and v′2. If θ1=38o, determine the speed of m2 after the collision, v2′=?. Express your answer in units of m/sm/s with one decimal place. Note: Please note that we do not know whether or not this is an elastic collision.
Important note: Unless otherwise stated, your answers must be in Sl units. Three pucks with masses m₁ = 25.0 [g], mB = 50.0 [g], and mc = 75.0 [g] approach the origin as they move on a frictionless table. Puck A moves with speed A = 3.50 [m/s] while puck B moves with speed up = 1.25 [m/s] and is oriented at B = 72.0-below the horizontal as shown. All the pucks arrive at the origin at the same time and stick together, causing it to move at 0.12 [m/s] to the + direction.

Hi there! I need some help! I am really confused. I do not know how to solve this! A block of mass m = 4.4 kg, moving on frictionless surface with a speed vi = 9.2 m/s, makes a perfectly elastic collision with a block of mass M at rest. After the collision, the 4.4 kg block recoils with a speed of vf = 2.5 m/s. Mass m is closest to: Thank you!
