In 1987, Marisa Canofoglia, of Italy, roller-skated at a record-setting speed of 40.3 km/h. If the magnitude of Canofoglia’s momentum was 660 kg∙m/s, what was her mass?

Mass = 58.98 kg

Explanation:

Given the following data;

Velocity = 40.3 km/h to meters per seconds (m/s) = 40.3*1000/3600 = 11.19 m/s

Momentum = 660kgm/s

To find the mass;

Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.

Mathematically, momentum is given by the formula;

Substituting into the equation, we have

660 = mass * 11.19

Mass = 660/11.19

Mass = 58.98 kg
