That the planets orbit around the sun
A.
Impulse is calculated through the equation,
I = mΔv
where I is impulse, m is mass and Δv is change is velocity. Substituting the known values,
I = (6 kg)(23 m/s - 6 m/s)
I = 102 kg m/s
<em>Answer: 102 kg m/s</em>
B.
Impulse in this item is calculated by multiplying the force by the time.
I = Force / time = (29 kg m/s²)(7 s) = 203 kg m/s
<em>Answer: 203 kg m/s</em>
C.
To answer this item, we have to multiply the mass and the velocity to get the impulse and divide the answer by the time to get the force.
F = m(v)/t
Substituting,
F = (0.1 kg)(-5.69 m/s)/0.64 s
F = -0.89 N
<em>Answer: -0.89 N</em>

Explanation:
V=u+at
where,
v=final speed
u=initial speed,(starting speed)
a=acceleration
t=time
- v=u+at = 6=2+a*2
6=2+2a
2a=6-2
2a=4
a=4/2 = 2
a =2
2. to find time taken
v=u+at
25=5*2t
2t=25-5
2t=20
t=20/2
t=10sec
3. finding final speed
v=u+at
v=4+10*2
=4+20
v=24m/sec
5.v=u+at
=5+8*10
=5+80
V=85m/sev
6. v=u+at
8=u+4*2
8=u+8
U=8/8
u=1
these are your missing values
Answer:
The tendeny of a body to continue its state either motion or rest is called inertia . First law of newton also called law of inertia .
There are three types of inertia
1. Motion inertia
2. Rest inertia
3. Directional inertia
