On a straight road (taken to be in the +x direction) you drive for an hour at 50 km per hour, then quickly speed up to 90 km per hour and drive for an additional two hours. Required:a. How far do you go?b. What is your average x component of velocity?c. Why isn't vavg, x equal to the arithmetic average of your initial and final values of vx, (50+90)/2 = 70 km per hour?

1 - wave length

2 - amplitude

3 - crest

4 - trough

explanation:

duh.

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.
