Rectilinear motion

Boojho was riding in his bicycle along a straight road. He classified the motion of various parts of the bicycle as (i) rectilinear motion, (ii) circular motion and (iii) both rectilinear as well as circular motion. Can you list one part of the bicycle for each type of motion? Support your answer with reason.

The particle moves with rectilinear motion given the acceleration-displacement (a-S) curve is shown in figure, determine the velocity after the particle has traveled 30 m. If the initial velocity is 10m/s

A plot of velocity versus time for a body in rectilinear motion is as shown in the figure.indicate whether acceleration is positive, negative , zero , variable or constant in the region OA, AB, BC and CD.Calculate the distance described up to the point C.What is the displacement up to point C ?

As given in the acceleration displacement (a-S) curve the particle moves in the rectilinear motion: Determine the velocity after the particle has traveled 20 m if the initial velocity is 10 m/s. a(m/s) 10 S(m) 10 20

For a particle under going rectilinear motion with uniform acceleration, the magnitude of displacement is one third the distance covered in some time interval. The magnitude of final velocity is less than magnitude of initial velocity for this time interval. Then the ratio of initial speed velocity to the final speed for this time interval is :

A bar of mass m resting on a smooth horizontal plane starts moving due to the force F=mg//3 of constant magnitude. In the process of its rectilinear motion the angle alpha between the direction of this force and the horizontal varies as alpha=as , where a is a constant, and s is the distance traversed by the bar from its initial position. Find the velocity of the bar as a function of the angle alpha .

Fig. shows thre velocity versus time curves for a particle in rectilinear motionalong a horizontal line. In each case, find the displacement of the particle over the time interval 0 le t le 4 , and explain what it tells you about the motion of the particle.
