In r4 you are given the points 2. 2 (a) write out all possible arrows which can be formed using the points p, q, r. - (hint: if your list of arrows is complete, there should be nine of them.) (b) for each of the arrows from part (a), find the vector it represents. (c) which pairs of vectors from part (b) are parallel?

c because the action was the roller coaster reaches bottom of hill (action) reaction would be blood tends to drain away from head

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.
