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).

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
