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

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?

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?

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
