Ahiker is walking down a straight road traveling due west. her journey can be thought of as occurring in 3 consecutive parts: traveling 95 minutes at 0.75 m/s, 75 minutes at 1.1 m/s, and then 26 minutes at 0.92 m/s. a. what is her velocity for each part?

Velocity in the first part= 0.75 m/s

Velocity in the second part=  1.1 m/s

Velocity in the third part= 0.92 m/s

Explanation:

Conceptual analysis : The velocity is defined by the following formula:

v= d/t

Where:

v : velocity in The speed in meters over second (m/s)

d : distance in meters (m)

t : time in seconds (s)

Problem development

velocity in the first part= 0.75 m/s

velocity in the second part=  1.1 m/s

velocity in the third part= 0.92 m/s

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
