Question

An object is moving along a horizontal line on the interval 1 ≤ t ≤ 3, where t is measured in seconds. The object has an initial position x(1) = 3 meters and a velocity of v(t) = 1.5t meters per second. Find the object’s position when t = 3 seconds.

Answer 1

I am not sure how to find this one at all.

Answer 2

this one is hard give me a min and what class is this

Answer 3

This sounds like physics to me.

Answer 4

ya I'm only in 8th grade taking 11th grade classes but i can try to help

Answer 5

I know. I am in eleventh grade. :) You are one smart kid.

Answer 6

thanks not to sure on this one maybe @Hero can help

Answer 7

I can help. This isn't all that bad.

Answer 8

It's general physics.

Answer 9

Perfect. I can probably do it, I just don't know what formula to use.

Answer 10

you don't need a formula

Answer 11

Awesome. how do you do it?

Answer 12

can you teach me to lol i want to know what i missed

Answer 13

Just plug t into the equation. (1.5)(3)

Answer 14

That'll give you your meters traveled.

Answer 15

Then just add it to your starting point of 3 meters.

Answer 16

See? Not so terrible.

Answer 17

If you understand the concept, there's no need for memorizing equations except for the very basics.

Answer 18

think i have ans but prob wrong. Since it's not my question ill wait for @watermelon16 to get it

Answer 19

Okay so 4.5 is my meters traveled

Answer 20

And then I add 3????

Answer 21

Did you get 7.5 meters? (1.5)(3)=4.5 then just add 3 because that was your starting point

Answer 22

Yes I got 7.5

Answer 23

you wouldn't expect to have to do that because most of the time, people set the starting point at zero.

Answer 24

Hope I was able to help!
