Question

A baseball player applies a constant force of 130.0 N over a period of 5.00 ms when he strikes a baseball with a mass of (0.130 kg). Find the final velocity of the ball if it initially hits the bat with velocity of (40 m/s)

Answer 1

The final velocity of the ball is 1006.15 m/s

Step-by-step explanation:

The final velocity of the baseball can be found using the formula:

vf = (Fa)(Δt) / m + vi

Where:

• vf is the final velocity of the ball
• Fa is the applied force on the ball
• Δt is the time interval over which the force is applied
• m is the mass of the ball
• vi is the initial velocity of the ball

Substituting the given values:

vf = (130.0 N)(5.00 × 10-3 s) / (0.130 kg) + 40 m/s

vf = 1006.15 m/s

Therefore, the final velocity of the ball is 1006.15 m/s.
