Ill has just gotten out of her car in the grocery store parking lot. the parking lot is on a hill and is tilted 3 degrees. fifty meters downhill from jill, a little old lady lets go of a fully loaded shopping cart. the cart, with frictionless wheels, starts to roll straight downhill. jill immediately starts to sprint after the cart with her top acceleration of 2.0m/s2.how far has the cart rolled before jill catches it?

is the time after which Jill will be able to catch the cart.

Explanation:

Given:

Now the component of gravity acting on the cart along the inclined plane:

Time taken by Jill to reach this speed:

where:

t = time taken

u = initial velocity = 0

is the time after which Jill will be able to catch the cart.

speed

ratio of distance traveled to time interval

net force

vector sum of forces on object

object

source of diverging light rays either luminous or illuminated

don't remove my answer im trying my best to answer them

explanation:

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
