What is the speed of the body moving with uniform acceleration at the midpoint of two points on a straight line, where the speeds are u and v respectively ?

Can a body with uniform acceleration always move in straight line?

Can a body subjected to a uniform acceleration always move in a straight line.

For a body moving with uniform acceleration along straight line, the variation of its velocity (v) with position (x) is best represented by

For a body moving with uniform acceleration along straight line, the variation of its velocity (v) with position (x) is best represented by

For body moving with uniform acceleration a , initial and final velocities in a time interval t are u and v respectively. Then its average velocity in the time interval t is

A train is moving with constant acceleration. When the ends of a train pass by a signal their speeds are u and v respectively. Calculate the speed of the midpoint of the train while passing the signal.

The speed of a body moving with uniform acceleration is u. This speed is doubled while covering a distance S. When it covers an additional distance S, its speed would become
