What does a constant velocity look like on a displacement vs time graph?
1 answer:
Answer:
A line with slope equal to the velocity.
Explanation:
If one is in the presence of constant velocity, that means that at the quotient between displacement and time elapsed is a constant value, therefore one can write the following equation:
therefore, solving for displacement we get:
which if plotted with displacement (D) on the vertical axis and time (t) on the horizontal axis, renders a line with slope equal to the constant value of the velocity (v):

Answer with Explanation:
Mass of block=1.1 kg
Th force applied on block is given by
F(x)=
Initial position of the block=x=0
Initial velocity of block=
a.We have to find the kinetic energy of the block when it passes through x=2.0 m.
Initial kinetic energy=
Work energy theorem:
Where Final kinetic energy
=Initial kinetic energy
Substitute the values then we get
Because work done=
Hence, the kinetic energy of the block as it passes thorough x=2 m=2.13 J
b.Kinetic energy =
When the kinetic energy is maximum then
Substitute x=
Substitute x=
Hence, the kinetic energy is maximum at x=
Again by work energy theorem , the maximum kinetic energy of the block between x=0 and x=2.0 m is given by
Hence, the maximum energy of the block between x=0 and x=2 m=2.48 J
