Answer:
176J
Explanation:
the explanation is that before the cat hits the ground the amount of kinetic energy builds up making it so that there is more energy
A Cat is a secondary source
Answer:
Explanation:
Given:
A = 589 J
D = 1 100 m
____________
F - ?
A = F·D
F = A / D = 589 / 1100 ≈ 0.54 N
Answer:
A drop of water falling from a faucet into a sink
Answer:
0.45 m/s in the negative x-direction
Explanation:
From the law of conservation of momentum, the sum of initial momentum equals the sum of final momentum
Momentum, p=mv where m is the mass and v is the velocity
where 
is the common velocity, 
and 
are velocities of magnet moving in positive x-direction and magnet moving in negative x-direction respectively, 
and 
are masses of magnet moving in positive x-direction and magnet moving in negative x-direction respectively.
Substituting 125 g for and 85 g for , 7.33 m/s , -11.9 m/s for then
Therefore, the velocity of single unit is 0.45 m/s in the negative x-direction
