Elastic collisions are collisions in which both
momentum and kinetic energy are conserved. I think the correct answer
from the choices listed above is option A. Two <span>glass marbles bounce off each other is an example of an elastic collision. Hope this answers the question.
I hope this helps! <3

Florida is aligned on the coast of the Gulf of Mexico. The Gulf is known for producing strong hurricanes due to its warm waters which hurricanes thrive on. Florida is hit by hurricanes pretty often.
Answer:
2 ms^2
Explanation:
Given that the mass of the refrigerator is 200Kg
The net force acting on the refrigerator is 400N
The time takes is 4s
From Newtons's second law of motion;
F =ma
a = F/m
a = 400/200
a = 2 ms^2
This is a constant acceleration
Answer:
2.26 s
Explanation:
Let's take down to be positive.
Given (in the y direction):
Δy = 25 m
v₀ = 0 m/s
a = 9.8 m/s²
Find: t
Δy = v₀ t + ½ at²
25 m = (0 m/s) t + ½ (9.8 m/s²) t²
25 = 4.9t²
t = 2.26 s
If the ball instead had an initial horizontal velocity of 5 m/s, its initial vertical velocity is still 0 m/s. So the time to fall is still 2.26 s.
