3 slices of a partially eaten 12-inch pizza are shown above. The CM of the entire uneaten pizza is cm = - 1.4 in. and yox= - 1.4 in, as shown.
(a) Assuming that each remaining slice is identical, find the CM of each slice. Choose the origin as shown above.
Starting with the slice in Q2 and going cow give the 3 CM's in the (x, y) format.
HINT: By symmetry, the positions of the CM of each slice must be the same distances x and y from the middle of the
pizza.
(b) Is the crust of the pizza stuffed with cheese? Prove your answer.

a.   mass number from atomic number

im guessing the west of station b

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s
