Question

7. A runner runs on the track field with a velocity of 20 m/s and it is known that her momentum is

1,200 kg*m/s. What is the weight of the runner?

Answer 1

Weight of the runner is 60 kilograms

Step-by-step explanation:

Momentum is the product of weight and velocity.

The formula is : p=mv where m is mass in kg and v is velocity in m/s

Given in the question ;

v= 20 m/s and p=1200 kg*m/s

Applying the formula as;

p= mv

1200 = m * 20

1200/20 = m

60 kg = m
