Heather and matt take 34 minutes to walk eastward along a straight road to a store 2.0km away. what is their average velocity in m/s

0.98 m/s eastward

Explanation:

The average velocity is defined as:

where

d is the displacement

t is the time taken to do the displacement

Here the displacement of Heather and Matt is

d = 2.0 km = 2000 m

While the time interval is

So, their average velocity is

and the direction is the same as the displacement (eastward).

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
