Answer 3

Hi, you there?

Answer 4

@SNIIX18 this is the question I need help in (:

Answer 5

HI to you two eric..

Answer 6

I can help, if SNIIX18 isn't able yet.

The car is accelerated because there is a force on it.
This causes it to gain \(20m/s\) in \(5s\). Can you tell me the acceleration, then?

Answer 7

is it E?

Answer 8

That's not what I got, and I think I did it correctly...

Answer 9

what did you get?

Answer 10

I won't just tell you! :P I don't often give answers. I make sure people get there themselves.

Answer 11

Answer 12

Answer 13

Haha, nope! Sorry. I want to see your work, or you learning, or your understanding!

Answer 14

And the "nope" was to your "just this once." I'm going to be stubborn, now, and not help you eliminate answers randomly. You'll have to get an answer from somebody else. I'll only guide you to it.

Answer 15

LMAO! I already found it don't worry!

Answer 16

Hm?

Answer 17

Found it for sure? Found acceleration, and multiplied that by mass to see what the force must be?

Answer 18

uggh i need help on same question this does not help

Answer 19
