If a 0.5kg toy car is rolling down a hill with a velocity of 0.8m.s, what is the car's momentum?
To find the momentum of an object, you can use the formula:
Momentum = mass × velocity
Given that the mass of the toy car is 0.5 kg and its velocity is 0.8 m/s, you can calculate the momentum as follows:
Momentum = 0.5 kg × 0.8 m/s
Momentum = 0.4 kg·m/s
Therefore, the car's momentum is 0.4 kg·m/s.
To find the car's momentum, we can use the formula:
Momentum = mass * velocity
Given that the mass of the car is 0.5 kg and the velocity is 0.8 m/s, we can substitute these values into the formula:
Momentum = 0.5 kg * 0.8 m/s
Multiplying the two values:
Momentum = 0.4 kg·m/s
Therefore, the car's momentum is 0.4 kg·m/s.
