List of top Physics Questions on Motion in a straight line asked in TS EAMCET

A body X is allowed to fall freely from a height of 125 m from the ground and another body Y is thrown at the same instant vertically upwards with a velocity of $50 ms^{-1}$ from the ground. The relative velocity of the body Y with respect to the body X when they cross each other is

For a particle moving along a straight line path, the displacements in third and fifth seconds of its motion are 10 m and 18 m respectively. The speed of the particle at time t=4s is

A person wearing a parachute jumps off a plane from a height of 2 km from the ground and falls freely for 20 m before his parachute opens. After his parachute opens if he continues to move uniformly with the velocity attained due to his freefall, the total time taken by the person to reach the ground is (Acceleration due to gravity = 10 ms$^{-2}$)

A particle initially at rest is moving along a straight line with an acceleration of 2 ms⁻². At a time of 3 s after the beginning of motion, the direction of acceleration is reversed. The time from the beginning of the motion in which the particle returns to its initial position is
