Question

(5) 5. A ballistic pendulum experiment is performed as shown in the diagrams below. The ball has a mass of 0.200 kg and the wooden block has a mass of 1.000 kg. Use the data in the diagrams to do appropriate calculations to determine if the collision is elastic or inelastic. (Hint: It should be possible to draw a conclusion without calculating any velocities.) Diagram 1 Part 1 Ball pendulum is released, striking block pendulum 2.50 cm Part 2 Ball pendulum rebounds Block pendulum responds to impact 50 cm 0.10 cm Answer:

Explanation / Answer

Inelastic collision, is one in which the colliding objects stick together upon impact. As a result, the velocity of the two colliding objects is the same after they collide.

so, we can conclude by observing the diagram that the pendulum is not stick with the wooden block, it rebounds after striking with block, therefore collision will elastic.

another way to determine the type of collision is to calculate the kinetic energy of the bodies before and after the collision. If kinetic energy is not conserved, then the collision is inelastic.
