A19.3 kg dog is running northward at 2.98 m/s , while a 6.26 kg cat is running eastward

v = 0.78 m/sec at 21.61° towards the east of north

Explanation:

Given a 19.3 kg dog is running northward at 2.98 m/s , while a 6.26 kg cat is running eastward at 3.64 m/s and the mass of the owner is 78.7 kg.

Given m(dog) = 19.3 kg and m(cat) = 6.26 kg

v(dog) = m/sec

v(cat) =   m/sec

Given the

Let the velocity of the owner be

We know that

v=0.78 m/sec

for direction

Tan(α)=

where α is the angle toward east of north.

Tan(α)=

α=21.61°

Global warming” refers to the rise in global temperatures due mainly to the increasing concentrations of greenhouse gases in the atmosphere. “Climate change” refers to the increasing changes in the measures of climate over a long period of time – including precipitation, temperature, and wind patterns.
