Answer:
v = -0.45 m/s
Explanation:
Assuming the canoe was initially at rest with momentum L = 0
and that the dog's velocity is in the positive direction
conservation of momentum
0 = 15(1.2) + 40v
v = -0.45 m/s
Answer:
change the
Explanation:
P = W/time
W = F*d
You have control over how fast you go up the stairs.
You also have control over how far up the stairs you go.
Therefore the answer is
If you don't like distance as an answer, you can carry something up the stairs -- anything that increases F will do.
C.figure 3 is the answer had the same and got is right
The kinetic energy is 
.
Explanation:
The kinetic energy of an object is given by
where
K is the kinetic energy of the object
m is the mass of the object
v is the speed of the object
For the comet in this problem, we have:
is its mass
is the speed
First, we convert the speed from km/h to m/s:
Therefore, the kinetic energy of the comet is
