Q
Q: A 3 kg block is sliding on a frictionless surface with a velocity of 4 m/s. What is the momentum of the block?
Solution:
Momentum p = mv = 3 kg * 4 m/s = 12 kg·m/s.
Steps: 5
Show Steps
Step 1: Identify the mass of the block. The mass is given as 3 kg.
Step 2: Identify the velocity of the block. The velocity is given as 4 m/s.
Step 3: Use the formula for momentum, which is p = mv (momentum = mass × velocity).
Step 4: Substitute the values into the formula: p = 3 kg * 4 m/s.
Step 5: Calculate the momentum: 3 kg * 4 m/s = 12 kg·m/s.
