m
s
.

Answer 1

@iambatman can u help me please?

Answer 2

can you describe what 'acceleration' tells us about velocity?

The question tells you the velocity is CONSTANT

Answer 3

I think it's D

Answer 4

ok thxs:)

Answer 5

ya

Answer 6

np

Answer 7

The graph represents the acceleration of two cars, Accel 1 and Accel 2, during a road trip. Which statement BEST describes the differences between the two cars' acceleration during the trip?












A)
Accel 1 accelerates throughout the entire trip; Accel 2 does not accelerate during the trip.



B)
Accel 1 rapidly accelerates and then stops; Accel 2 maintains a constant velocity during the trip.



C)
Accel 1 has a constant rate of acceleration; Accel 2 accelerates at different rates during the trip.



D)
Accel 1 accelerates for the first two-thirds of the trip; Accel 2 has a constant rate of acceleration.

Answer 9

I think c

Answer 10

is there anymore you need help on

Answer 11

Which BEST describes the difference between speed and velocity?












A)
Velocity is instantaneous.



B)
Speed is a vector quantity.



C)
Speed includes rate of change and direction.



D)
Velocity includes rate of change and direction.

Answer 12

I think c

Answer 13

@Dez77 @Kwadz you are wrong

The answer is not D to the first question.

A straight answer like "D" does not give the OP any help (especially when it is wrong) please try to GUIDE the OP to an answer for herself

Answer 14

okay @MrNood

Answer 15

man u need to sp@MrNood:(

Answer 16

acceleration is 'rate of change of velocity'

the question states that "the car is traveling at a constant velocity "

so what is the rate of change of velocity?

Answer 17

I think is b

Answer 18

Im thinking its A now

Answer 19

@Kwadz its A

Answer 20

I'm thinking that you are not thinking - PLEASE read and CONSIDER what I posted above

the question states that "the car is traveling at a constant velocity "

so what is the rate of change of velocity?
