If an object starts from 'A' and comes back to 'A', its displacement will be______

A particle starts from rest and has acceleration of 2 ms-2 for 10 s. After that it travels for 30 s. with constant speed and then undergoes a constant retardation of 4 ms and comes back to rest. The total distance covered by the particle is:

An object has moved through a distance can it have zero displace ment? If yes, support your answer with an example.

A ball is thrown upwards and it goes to the height 100m and comes down. (1) What is the net displacement? (2) What is the net distance?

An insect starts from a point and travels in a straight path 1 mm in the first second and half of the distance covered in the previous second in the succeeding second. In how much time would it reach a point 3 mm away from its starting point.

A body moves along a circular track of radius R. It starts from one end of a diameter and reaches the other end of diameter. What is the ratio of the distance travelled by the body to its displacement :

One mole of an ideal gas is taken from A to B , from B to C and then back to A . The variation of its volume with the temperature for that change is as shown . Its pressure at A is P_(0) , volume is V_(0) . Then , the internal energy .

A body starting from rest moves with constant acceleration 'a'. This acceleration is a pr where p is a constant. What is the displacement of particle in a time interval=0 to t = t_1 ?
