Step-by-step explanation:
A.9 kg toy car has a momentum of 5 kg*m/s. What is the car's speed?
The momentum of an object is defined as the product of its mass and velocity:
p = m * v
where p is the momentum, m is the mass, and v is the velocity.
To find the car's speed, we can rearrange this equation to solve for v:
v = p/m
Substituting the given values, we get:
v = 5 kg*m/s / 9 kg
v ≈ 0.56 m/s
Therefore, the speed of the car is approximately 0.56 m/s.
