Question

**Problem Statement:**

A pitcher claims he can throw a 0.140-kg baseball with as much momentum as a 2.34-g bullet moving with a speed of \(1.50 \times 10^3\) m/s.

**Questions:**

(a) What must the baseball's speed be if the pitcher's claim is valid?

[Answer Box] \( \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\) m/s

(b) Which has greater kinetic energy, the ball or the bullet?
- ○ The ball has greater kinetic energy.
- ○ Both have the same kinetic energy.
- ○ The bullet has greater kinetic energy.

**Problem:**

An object has a kinetic energy of 290 J and a momentum of magnitude 20.8 kg·m/s.

(a) Find the speed of the object.
[Answer Box] m/s

(b) Find the mass of the object.
[Answer Box] kg

**Explanation:**

This problem involves calculating the speed and mass of an object using its kinetic energy and momentum. You can use the following formulas:

1. Kinetic Energy (KE) = \( \frac{1}{2}mv^2 \)

2. Momentum (p) = \( mv \)

Where:
- \( m \) is the mass of the object,
- \( v \) is the speed of the object.

To solve the problem:
- Use the given kinetic energy and momentum to form two equations.
- Solve these equations simultaneously to find the values of \( v \) and \( m \).
