Answer:
Explanation:
Given,
mass of the object,m = 0.30 Kg
initial speed, v_i = 3 m/s
time of collision = 0.20 s
final speed, v_f = -4 m/s
Impulse = change in momentum
Hence, impulse of the object is equal to
D all of them is the answer. All three can be used to celebrate sporting events
Since we are ignoring air resistance which is a non-conservative force, the potential energy will be completely converted into kinetic energy, resulting in a final kinetic energy of
.
Answer:
F-ma
Explanation:
If you are speaking of objects like satellites, etc. then their mass is much less than that of the Earth. A good approximation is Newton's first law of motion:
Force
=
Mass × Acceleration
often written:
F
=
m

The gravitational force is the same between the Earth and the object - only the mass differs. So the acceleration is inversely proportional to the mass.
Answer:
Kinetic friction is lesser than limiting friction. Two surfaces are rubbed together, first with a smaller force and then with a greater force.
