A student says "An object moving at a speed of 20ms^-1 will always be moving faster than an object that has an acceleration of 5ms^-2 ". Do you agree with this statement? If you don't then explain why

help pls

OpenStudy (anonymous):

I don't know, I'm not to good with velocity, sorry. :(

OpenStudy (adi3):

np

OpenStudy (baru):

object A: moving at constant velocity of 20m/s Object B: "accelerating" at 5m/s^2

OpenStudy (baru):

do you know what acceleration is?

OpenStudy (adi3):

yes abviously

OpenStudy (baru):

so, what is acceleration?

OpenStudy (adi3):

increase in speed

OpenStudy (baru):

if a body has zero velocity initially, and acceleration 5 m/s^2, what is its velocity after 5 seconds?

OpenStudy (baru):

@Adi3

OpenStudy (adi3):

5

OpenStudy (baru):

after '5' seconds have passed, and the body is accelarting by 5 every second, what will its velocity be?

OpenStudy (adi3):

25

OpenStudy (baru):

object A: moving at constant velocity of 20m/s Object B: "accelerating" at 5m/s^2 is A always faster than B?

OpenStudy (adi3):

not always right?

OpenStudy (baru):

yes, you just showed that after 5 seconds B is faster than A

OpenStudy (adi3):

thanks man

OpenStudy (baru):

np :)
