Can equation of Kinematics be used in a situation where the acceleration varies in time?Can they be used when acceleration is zero?

Graph of velocity (v) versus time 't' for motion of a motorbike which starts from rest and moves along a stright road is given . (a)Find the average acceleration for the time interval t_(0) =0 to t_(1) =6.0 s (b) Estimate the time at which the acceleration has its greatest positive value and the value of the acceleration at that instant. (c) When is the acceleration is zero ? (d) Estimate the maximum negative value of the acceleration and the time at which it occurs.

The acceleration of a moving body can be found from

The acceleration of a moving body can be found from

Cyclotron is used to accelerate

Give an example where the velocity of an object is zero but its acceleration is not zero.

Position-time graph for motion with zero acceleration is

Give examples for the particle where (a) the velocity is in opposite direction to the acceleration (b)the velocity of the particle is zero but is acceleration is not zero.

A car moving along a circular track of radius 50.0m acceleration from rest at 3.00 ms^(2) Consider a situation when the car's centripetal acceleration equal its tangential acceleration

When the velocity of a body executing shm is zero its acceleration is not zero. Why?

Statement-1: When velocity of a particle is zero then acceleration of particle must be zero at that instant Statement-2: Acceleration is equal to a= v ((dv)/(dx)) , where v is the velocity at that instant .
