Motion Test - 2...

From kinematics, correct equation of motion for $$S$$ is/are :

Is it possible to have an accelerated motion with a constant speed? Name such type of motion.

Which of the following quantity remains constant in a uniform circular motion?

The distance $$x$$ covered in time $$t$$ by a body having initial velocity $${ v }_{ 0 }$$ and having constant acceleration $$a$$ is given by $$x={ v }_{ 0 }t+1/2a{ t }^{ 2 }$$. This result follows from :

A food packet is released from a helicopter rising steadily at the speed of $$2\ { m }/{ s }$$. After $$2$$ seconds the velocity of the packet is (Take $$g=10  { m }/{ { s }^{ 2 } } $$):

Which of the following is/are true about retardation

For a body moving with an initial velocity $$u$$ and uniform acceleration $$a$$. Find the displacement of the body in time t.
