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?

Weight of the runner is 60 kilograms

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

i guess that visual aids present persuasive examples to what you are presenting, some factors would be theme (does it fit with the color, information, what you are presenting), size (can you see it, is it a big enough span of data/information), and overall look of the visual aid.

hope this : )
