You are playing ice hockey with friends on a frozen pond. The hockey puck (mass 0.2 kg) is sliding on the ice at 10 m/s when it
chubhunter [2.5K]

Answer:

The mass of the hailstone is  m_2 = 0.05

Explanation:

From the question we are told that

    The mass of the hockey puck is m_1  = 0.2 \ kg

     The initial speed of the puck is u_1 =  10 \ m/s

      The final speed of the puck is  v_f  =  8 \ m/s

According to the principles of linear momentum

      m_1u_1 + m_2u_2 = (m_1 + m_2)v_f

At initial the velocity of the hailstone was zero so

       u_2 =  0 \ m/s

So  

     m_1 u_1 =  (m_1 + m_2 )v_f

substituting values

        0.2 *  10 =  (0.2 + m_2 )* 8

=>     2 =  (0.2 + m_2 )* 8

=>     0.25 = 0.2 + m_2

=>    m_2 = 0.05

Mashutka [201]

He does not have much endurance since he is new to exercise. This explains best why Guillermo is struggling.

<h3>What is Endurance?</h3>
  • An organism's capacity to exert itself and remain active for a prolonged period of time, as well as its capacity to resist, withstand, recover from, and have immunity to trauma, wounds, or exhaustion, are all examples of endurance (also related to sufferance, resilience, constitution, fortitude, and hardiness). Usually, it is employed in anaerobic or aerobic exercise.
  • Depending on the type of activity, "long" can mean anything from minutes for high-intensity anaerobic exercise to hours or days for low-intensity aerobic exercise.
  • Unless a person additionally engages in resistance training to offset this effect, training for endurance can impair the ability to exert endurance strength.
