Given: The mass of the body \( m = 10 \, \text{kg} \), and the speed \( v = 5 \, \text{m/s} \).
Step 1: Use the formula for momentum The momentum \( p \) is given by the formula: \[ p = m \times v \]
Step 2: Substitute the values Substitute the given values into the formula: \[ p = 10 \times 5 = 50 \, \text{kg m/s} \]
Answer: The correct answer is option (1): 50 kg m/s.
