A. 2.1 m/s2
B. 17.85 m/s2

@zepdrix @whpalmer4 @paki

Answer 6

In general, F(orce)=m(retrice\(\times\)a(cceleration, or \(F=ma\). So if you solve that for a, you can use it to find the acceleration.

Answer 7

bah. It munged the mass thing... anyhow.

Answer 8

is it A

Answer 9

@e.mccormick

Answer 10

Yah, that should be it since all your units are standard (kg and N).

Answer 11

ok i have 3 more can you help

Answer 12

Well, I know the basic equations, but never took physics...

Answer 13

Mr. Temper was late for work one morning when his car broke down on the side of the road. After many failed attempts to restart the car, Mr. Temper was so angry that he kicked his car's tire and sprained his foot.

Which of Newton's laws of motion should Mr. Temper have thought about before kicking the car?
A. Newton's first law
B. Newton's third law
C. Newton's fourth law
D. Newton's second law

Answer 14

third law.. for every action there is an equal and opposite reaction :)

Answer 15

thanks

Answer 16

Which of Newton's laws of motion best illustrates the principle of inertia?
A. Newton's first law
B. Newton's third law
C. Newton's second law
D. Newton's fourth law

Answer 17

first law.. that deals with inertia..

Answer 18

Cheryl has just climbed the steps of the metro bus. She begins walking 10 meters to the back of the bus at a constant speed of 3 miles per hour. At the same time, the bus begins moving forward at a constant speed of 3 miles per hour.

When Cheryl arrives at the back of the bus...
A. she will have moved 5 meters relative to the bus.
B. she will have moved 20 meters relative to the Earth.
C. she will not have moved relative to the Earth.
D. she will have moved 10 meters relative to the Earth.

Answer 19

Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.

Answer 20

one more please

Answer 21

sure

Answer 22

i ges she wud not have moved relative to the earth..

Answer 23

So C

Answer 24

cause the 10 meters she moved back is cancelled by the movemnt o the bus

Answer 25

yes :)

Answer 26

ok thanks thats all

Answer 27

ok :)
