Answer 1

You throw a baseball straight up at 25m/s. What is its velocity 3 seconds later?
5m/s
-m/s
28m/s
-28m/s
112.5m/s

Answer 2

X= viT + 1/2at^2

Answer 3

Right?

Answer 4

\[\large v_f = v_i + at\]

Answer 5

What's the difference

Answer 6

lol everything. Compare the equations.

vi = 25
a = -9.8
t=3

Answer 7

I got -735

Answer 8

Srry...
-4.4

Answer 9

Idk. You did not listen to what i said in the last one.

Answer 10

OMG yes I did gee

Answer 11

Rounded would be -5

Answer 12

Right?

Answer 13

I said show work! You need to listen!

Answer 14

It's on my paper I swear lol.
I have vf=vi+at
vi=25
a=-9.8
t=3
25+(-9.8)(3)=-4.4

Answer 15

I can't see your paper!

Answer 16

Good

Answer 17

is tht right

Answer 18

YES THE WORD GOOD MEANS YES

Answer 19

oh lol hahha

Answer 20

A turtle sits on a log. If the action of the Earth is a downward force on the turtle, then the reaction is the....
A. upward force the Earth exerts on the turtle
B. upward force the turtle exerts on the Earth
C. normal force the turtle exerts on the log
D. normal force the log exerts on the turtle
E. buoyant force the log exerts on the ground

Answer 21

B. upward force the turtle exerts on the Earth

Answer 22

A bucket on the end of a string is used to pull water out of a well. If the water and the bucket have a combined mass of 12kg, and the bucket accelerates upward at 2.0m/s^2, what is the tension in the string?
zero
10N
72N
120N
144N

Answer 23

Fnet = ma
m is mass, a acceleration

Fnet = T - mg
or
ma = T - mg

plug in the mass m, g is gravity, 9.8, find T

Answer 24

I can use either of those?

Answer 25

Well you could but just use the last one

Answer 26

9.8 is for gravity or what?

Answer 27

g=gravity=9.8

Answer 28

12kg(2.0)^2=T-12(9.8)
48/-117.6 = -117.6/-117.6
-.408

Answer 29

no. ma = T - mg.

Answer 30

OMG wtf am I doing wrong??

Answer 31

the a is not squared

Answer 32

And i have no idea why you divided

Answer 33

12*2.0= T - 12*9.8

Answer 34

I was dividing to get T by itself dumass

Answer 35

well don't divide to get T by itself dumbass

Answer 36

Why is dumbass acceptable but retriceisn't

Answer 37

see. a.ss is unacceptable.

Answer 38

I'm getting 24=-117.6
NOW what

Answer 39

12*2.0= T - 12*9.8

where did the T go

And you only need to add things to both sides to get T by itself

Answer 40

I multiplied and got -117.6t on one side
So I'd add 24+-117.6???

Answer 41

24 = T - 117.6

Just add 117.6 to both sides.

Answer 42

-141.6?
So 144N?

Answer 43

w/e 24+117.6 is

Answer 44

-141.6!!!!!!

Answer 45

Postitive

Answer 46

Why is it negative!

Answer 47

I corrected myself. Get glasses yo!

Answer 48

Get it correct the first time, yo!

Answer 49
