a chunk of clay in the shape of Bugs Bunny has a mass of 0.75 and an initial velocity of 5.0 m/s to the right. a second chunk of clay is in the shape of Elmer Fudd has a mass of 0.25 kg and an initial velocity of 3.0 m/s to the left. what is the composite velocity ater the clay figures collide?
BBmass*5+EFmass*(-3)=(BBmass+EFmass)V
solve for V
lol 1-2
To determine the composite velocity after the clay figures collide, we can use the principle of conservation of momentum. According to this principle, the total momentum before the collision is equal to the total momentum after the collision.
The momentum of an object is calculated by multiplying its mass by its velocity. So, first, we calculate the initial momentum of each clay figure:
Momentum of Bugs Bunny = mass of Bugs Bunny x velocity of Bugs Bunny
= 0.75 kg x 5.0 m/s
= 3.75 kg·m/s (to the right)
Momentum of Elmer Fudd = mass of Elmer Fudd x velocity of Elmer Fudd
= 0.25 kg x (-3.0 m/s) (Note: Negative sign indicates velocity to the left)
= -0.75 kg·m/s (to the left)
Now, to find the composite velocity after the collision, we equate the total momentum before the collision to the total momentum after the collision:
Total initial momentum = Total final momentum
(3.75 kg·m/s) + (-0.75 kg·m/s) = Total final momentum
3.0 kg·m/s = Total final momentum
Therefore, the composite velocity after the clay figures collide is 3.0 m/s. Since the initial velocities have opposite directions, the composite velocity will have a positive sign, indicating motion to the right.
