Question

which skateboarder has greater momentum?*skateboarder a: mass = 60 kg; velocity = 1.5 m/sskateboarder b: mass = 50 kg; velocity = 2.0 m/s

Explanation:

Step1: Calculate momentum of Skateboarder A

Momentum formula: \(p = mv\) (where \(p\) is momentum, \(m\) is mass, \(v\) is velocity). For Skateboarder A, \(m = 60\space kg\), \(v=1.5\space m/s\). So \(p_A=60\times1.5 = 90\space kg\cdot m/s\)

Step2: Calculate momentum of Skateboarder B

For Skateboarder B, \(m = 50\space kg\), \(v = 2.0\space m/s\). So \(p_B=50\times2.0=100\space kg\cdot m/s\)

Answer:

Skateboarder B has greater momentum.
