A motorycle having a mass of 300 grams covers a distance of 6 kilometers west in 3 hrs.Determine the momentum of the motorcycle
Good Day....
Problem:
A motorcycle having a mass of 300 grams covers a distance of 6 kilometers west in 3 hrs.Determine the momentum of the motorcycle.
Note:
- the unit of the given mass is grams, we have to convert first grams to kilograms. 1 kg = 1000 grams. 300 grams × 1 kg / 1000 grams = 0.3 kg
- Convert the given velocity to m/s. 1 km = 1000 m and 1 hr = 3600 s
6 km/ 3 hours = 2 km/hr
2 km/hr × 1000 m / 1 km × 1 hr / 3600 s = 0.56 m/s
Given Data:
m (mass) = 300 grams or 0.3 kg
v (velocity) = 2 km/hr ( 0.56 m/s) west
p (momentum) = ? unknown
Solution:
The formula for momentum is momentum = mass × velocity ( p = mv )
p = mv
= 0.3 kg × 0.56 m/s
= 0.168 kg.m/s
Answer:
The momentum of the motorcycle is 0.168 kg.m/s
Hope it helps...=)
