Answer:-
Given:
First Object:
Mass (m₁) = 5 kg
Initial Velocity (u₁) = 0 m/s
Final velocity (v₂) = 16 m/s
time = 5 s
We know that,
Force = mass * acceleration
And acceleration = (v - u) / t.
Hence,
F₁ = 5 * (16 - 0) / 5
→ F₁ = 5 * 16/5
→ F₁ = 16 N
Second Object:
Mass (m₂) = 8 kg
Initial Velocity (u₂) = 0 m/s
Final Velocity (v₂) = 15 m/s
Time = 5 s
Hence,
F₂ = 8 * (15 - 0) / 5
→ F₂ = 8 * 15/5
→ F₂ = 24 N
Additional Information:
Force:
- It is the push or pull of an Object.
- It is a vector quantity.
- It is denoted by "F".
- F = ma, where m is the Mass of the Object and a is it's acceleration.
- It's units are Newtons (N) and dynes (dyn).
- It depends on mass & acceleration of the object.
