Answer 3

any ideas? haha

Answer 4

@surry99

Answer 5

no image is coming up for me to see

Answer 6

ok i see it now.

Answer 7

ok so force vs time is constant and the force is negative...agreed?

Answer 8

yes

Answer 9

ok so is the force is negative and constant what does that tell you about acceleration?

Answer 10

acceleration is zero?

Answer 11

no...try again...F=ma and force is negative and constant

Answer 12

acceleration is negative as well then? idk lol

Answer 13

yes acceleration is negative....good.
so if the acceleration on an object is negative is it speeding up of slowing down?

Answer 14

slowing down

Answer 15

good...now you need to look for a kinematic equation that relates position. time and acceleration.

Answer 16

d=1/2 at^2+(vi)t?

Answer 17

sure that will work...now assume the acceleration is some negative number.
If you started graphing d vs t starting at t = 0, what shape would you get?

Answer 18

would it be like a parabola

Answer 19

oh wait thats not right

Answer 20

yes parabola is correct but would it open up or down.

Answer 21

oh open down
