What is true of potential energy? select all that apply

a. it is described as stored energy

b. it can be observed in a puppy sitting in on a chair. not moving.

c. it is found in batteries, springs, a ball being held above the ground.

d. it’s symbols are PE

when the velocity of a mass on a spring is zero, the acceleration is at a maximum .

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000

1.195000

explanation:

total mass=0.0117+0.0137+0.0881+0.0111

total mass= 0.01172kg

total velocity = 0.283-0.743+0.871-0.799+0.155+0.637+0.301=0.102

momentum=mv=0.1172*0.102=1.195000//
