Given :
Mass of bus = 2000kg
Velocity of bus = 60km/h (uniform)
To Find :
Net force acting on bus
Concept :
➝ As per newton's second law of motion, Force is defined as the product of mass and acceleration. [F = ma]
➝ We know that, acceleration of body moving with uniform (constant) velocity is zero
Calculation :
⇒ F = ma
⇒ F = 2000 × 0
⇒ F = 0 N
Hence, net force acts on bus = zero.
Given ,
As we know that ,
and
In uniform velocity of object , the acceleration is zero
Thus ,
F = 2000 × 0
F = 0 N
The net force acting on a bus is 0 N
