The momentum of the traveling truck is 30000 kgm/s.
We need to know about momentum to solve this problem. Momentum can be defined as the degree of difficulty to stop a moving object. It can be determined by
P = m . v
where P is momentum, m is mass and v is velocity.
Momentum also can be defined by kinetic energy
KE = 1/2 . m . v²
KE = P² / 2m
where KE is kinetic energy
From the question above, the given parameters are :
m = 1200 kg
v = 25 m/s
By using the momentum formula, we get
P = m . v
P = 1200 . 25
P = 30000 kgm/s
