The size of force B is 3800 N.
What is force?
This can be defined as the product of the mass and acceleration of a body.
From the diagram attached,
Formula:
- Fa-Fb = ma................... Equation 1
Where:
- Fa = Size of Force A
- Fb = Size of Force B
- m = mass of the car
- a = Acceleration of the car
make Fb the subject of the equation
- Fb = Fa-ma................ Equation 2
From the question,
Given:
- Fa = 5000 N
- m = 800 kg
- a = 1.5 m/s²
Substitute the given values into equation 2
- Fb = 5000-(800×1.5)
- Fb = 5000-1200
- Fb = 3800 N.
Hence, The size of force B is 3800 N.
