Which of these situations would not qualify as a perfectly inelastic collision? a. a frog that jumps onto and sits on a lily pad.
b. a bowling ball that knocks pins out of its way as it rolls down a lane
c. a fish, swimming in one direction, that comes upon and swallows another fish swimming towards it
d. a piece of bubble gum that flies through the air and sticks to a golf ball at rest

Option (B)

Explanation:

In a perfectly inelastic collision, the two bodies collide each other after the collision.

A. As the frog and the lily pad stick together so it is a perfectly inelastic collision.

B. The bowling ball and the pin do not stick together so it is not an example of perfectly inelastic collision.

C. A fish swallows the another, so it is a perfectly inelastic collision.

D. Bubble gum sticks to the golf ball so it is a perfectly inelastic collision.

c)as speed changes, wavelength and frequency change.

everything changes!

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
