One dimensional problems

Figure gives the x-t plot of a particle is one dimensional motion. Give the signs of position, velocity and acceleration of the particle at t = 0.3s

The velocity-time graph of a particle in one-dimensional motion is shown in the figure. Which of the following formulae is correct for describing the motion of the particle over the time interval t_1 to t_2 ?

For a particle in one dimensional motion, the instantaeous speed is always equal to the magnitude of instantaneous velocity. Why ?

Assertion : Simple harmonic motion is an example on one dimensional motion with non-uniform acceleration . Reason : In simple harmonic motion, acceleration varies with displacement linearly.

A body is initially at rest. It undergoes one dimensional motion with constant acceleration. The power delivered to it at time t is proportional to

During one dimensional motion on x-axis Velocity time graph for particle is given. Average acceleration between (t = 0 sec) to (t = 6 sec)

Assertion : In one dimensional motion of an object, path length comes out to be equal to displacement. Reason : Direction of object is changed two times.

Projectile motion is a two dimensional motion with constant acceleration. Is this statement true or false?
