A306 g cart moves on a horizontal, frictionless surface with a constant speed of 14.2 cm/s. a 76.3 g piece of modeling clay is dropped vertically onto the cart. if the clay sticks to the cart, find the final speed of the system. answer in units of cm/s.

To solve this problem it is necessary to apply the concepts related to the conservation of the momentum for an inelastic shock. Mathematically this can be described as

Where,

m_{1,2} = Mass of each object

v_{1,2} = Initial velocity of each object

V_f = Final Velocity

If we assign the value of mass 1 and speed 1 to the cart and the variable of mass 2 to clay (which is at rest) we will have:

Therefore the final speed of the system would be 11.36cm/s
