Figure shows the displacement (x) -time (t) graph of the particle moving on the x-axis.

Which of the following statements is incorrect?

Which of the following graphs represents the position-time graph of a particle moving with negative velocity?

A particle is released from rest from a tower of height 3h. The ratio of the intervals of time to cover three equal heights h is:

A football is kicked into the air vertically upwards with velocity $$u$$. The velocity of the ball at the highest point is:

Which parameters shown below are common between uniform circular motion and uniform linear motion

A body dropped from a height $$h$$ with initial velocity zero, strikes the ground with a velocity $$3m/s$$. Another body of same mass dropped from the same height $$h$$ with an initial velocity of $$4m/s$$. The final velocity of second mass, with which it strikes the ground is

For the V-t graph shown displacement during 15 seconds is 

A force of $$5\ N$$ acts on a $$15\ kg$$ body initially at rest. The work done by the force during the first second of motion of the body is
