Answer:360 kg m/s
Explanation:Momentum refers to an object's quantity of motion.
Formula for Momentum: p=mv
p = refers to the momentum
m = refers to the object's mass (this is represented by the unit kg or kilogram)
v = this refers to the object's velocity (this is represented by the unit m/s or meter per second)
So, given that the bike has a mass of 18 kg and is traveling at 20 m/s, then you can already get the momentum by multiplying both of these values.
p = the bike's momentum (what is being asked here)
m = 18 kg
v = 20 m/s
Thus, p = 18kg × 20 m/s = 360 kg m/s
The bike's momentum is 360 kg m/s.
