If a 0.18 kg baseball has a momentum of p = 9.4 kg·m/s as it is thrown from home to second base, what is its velocity?
m/s toward second base
To find the velocity of the baseball, we can use the equation for momentum:
Momentum (p) = mass (m) × velocity (v)
Given that the mass of the baseball is 0.18 kg and the momentum is 9.4 kg·m/s, we can rearrange the equation to solve for the velocity:
v = p / m
Plugging in the values:
v = 9.4 kg·m/s / 0.18 kg
The velocity of the baseball, when rounded to two decimal places, is approximately 52.22 m/s towards second base.
To find the velocity of the baseball, we need to use the equation for momentum:
Momentum (p) = mass (m) * velocity (v)
In this case, we are given the momentum (p) as 9.4 kg·m/s and the mass (m) as 0.18 kg.
So, we can rearrange the equation to solve for velocity (v):
v = p / m
Substituting the given values into the equation:
v = 9.4 kg·m/s / 0.18 kg
Now we can calculate the velocity:
v ≈ 52.22 m/s toward second base
Therefore, the velocity of the baseball is approximately 52.22 m/s toward second base.
