Question

someone please help :(there is one example too, please show me your work

1. A 5.00 kg bowling ball is rolling at 6.00 m/s. What is the bowling balls momentum.
2. A car with mass 1200. kg has momentum 24 000 kg m/s. How fast is the car traveling.

Example: Your physics teacher is walking at 2.00 m/s. His momentum is 300. kg m/s. What is his mass?
v = 2.00 m/s ; p = 300. kgm/s ; m = ?
p = m*v ; m = p / v ; m = (300. kgm/s) / (2.00 m/s) ; m = 150. kg

    The answer for the following equation is mentioned below.

    • Therefore the momentum of the ball is 30.00 kg m/s
    • Therefore the velocity of the car is 20.0 m/s

    Explanation:

    1. Given:

    mass of the ball (m) = 5.00 kg m/s

    velocity of the ball (v) = 6.00 m/s

    To calculate:

    momentum of the ball (p)

    We know;

    To calculate the momentum of the ball (p);

            p = m × v

    where;

    p represents momentum

    m represents the mass

    v represents the velocity

      p = 5.00 × 6.00

      p = 30.00 kg m/s

    Therefore the momentum of the ball is 30.00 kg m/s

    2. Given:

    mass of the car (m) = 1200 kg

    momentum of the car (p) =24000 kg m/s

    To calculate:

    velocity of the car (v)

    We know;

    To calculate the velocity of the car;

    p = m × v

    where,

    p represents the momentum

    m represents the mass

    v  represents the velocity

         v = p÷m

         v = \frac{24000}{1200}

         v = 20 m/s

    Therefore the velocity of the car is 20.0 m/s
