Question

Another pitcher throws the same baseball in a straight line. Its momentum is 2. 1 kg·m/sec. What is the velocity of the ball?.

Answer 1

The velocity of the baseball with a momentum of 2.1 kg m/s and a mass of 0.5 kg is calculated to be 4.2 m/s using the formula for momentum.

Step-by-step explanation:

To find the velocity of the baseball when its momentum is given, we can use the formula for momentum which is momentum (p) = mass (m) × velocity (v). According to the information provided, we have the momentum of the baseball and its mass:

• Momentum, p = 2.1 kg·m/s
• Mass, m = 0.5 kg

We need to rearrange the formula to solve for velocity. So, the velocity (v) can be calculated as:

v = p / m

Substituting the given values:

v = 2.1 kg m/s / 0.5 kg

v = 4.2 m/s

Therefore, the velocity of the baseball is 4.2 m/s.
