Below you will see diagrams showing a trip taken by Fred and a trip taken by Frank. For each person, find their distance, displacement, average speed, and average velocity from A to B. Each square is 10 meters wide, and use words like north, south, east, and west for direction. The first thing Fred did was go south for 4 seconds. If he wanted to cut his average speed in half, how long should that southward motion last (assuming the other two motions happen in the same time as shown)? Explain your reasoning.

Would this amount of wait-time also have halved his average velocity?

i need the answer to this too but idk it ; -;

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.
