Question

A car's velocity after each consecutive second of motion is 2m/s , 4 m/s ,6m/s . This evidence that the car is


A. Moving with a constant speed
B. Moving with a constant acceleration
C. Moving with a constant velocity

Answer 1

Hey

Answer 2

at t=0 , u=2m/s
at t=2, u=4 m/s
at t==3, u =6 m/s

as u can see the data is following the equation v=u+at.

So the body is moving with constant acceleration

Answer 3

Which of the following represents an accelerated motion ? Select all that apply ; do not include commas or spaces ...

A an object that turns around and changes directions .

B. An object that changes its velocity
C. An object moving at at constant speed in the same direction.
D. An object that remains the at rest
E. An object moving in a circle at constant speed .
F. None of these

Answer 4

I assume they mean non-zero acceleration.

If an object is changing speed or velocity, or direction, then it is accelerating.
