Answer: A (Ft)
Explanation: The impulse experienced by the object equals the change in momentum of the object. In equation form, F • t = m • Δ v
cause an object to accelerate in a direction opposite to the unbalanced force
Explanation:
An unbalanced force is defined as any force that causes an object to accelerate in a direction opposite to the unbalanced force.
The unbalanced force is the net or resultant force describe in newton's second law of motion.
In the first law, it is the external force that causes the motion of a body to change.
Unbalanced forces can cause body to either accelerate in the direction of the force or in an opposite direction of the force.

Answer:
12 kg
Explanation:
Momentum before collision = momentum after collision
m₁ u₁ + m₂ u₂ = m₁ v₁ + m₂ v₂
After the collision, they have the same velocity, so v₁ = v₂ = v:
m₁ u₁ + m₂ u₂ = m₁ v + m₂ v
m₁ u₁ + m₂ u₂ = (m₁ + m₂) v
We know that m₁ = 6 kg, u₂ = 0 m/s, and v = u₁ / 3.
(6 kg) u₁ + m₂ (0 m/s) = (6 kg + m₂) (u₁ / 3)
(6 kg) u₁ = (6 kg + m₂) (u₁ / 3)
6 kg = (6 kg + m₂) (1/3)
18 kg = 6 kg + m₂
m₂ = 12 kg
Answer:
I = 0.0025 kg.m²
Explanation:
Given that
m= 2 kg
Diameter ,d= 0.1 m
Radius ,
R=0.05 m
The moment of inertia of the cylinder about it's axis same as the disc and it is given as
Now by putting the all values
I = 0.0025 kg.m²
Therefore we can say that the moment of inertia of the cylinder will be 0.0025 kg.m².
