Lesson: Kinematic Equations

A particle is moving in a straight line such that its acceleration and its initial velocity is 39 m/s. Find its displacement during the time interval from to .

A particle moves along the -axis in the direction of increasing. It starts at with an initial velocity of 47 cm/s and moves with uniform acceleration of 51 cm/s² in the same direction as its motion. Determine its velocity and its displacement from the origin after 6 seconds.

A particle was observed moving in a straight line. Its velocity was measured 7 seconds after it was first observed and was found to be 188 cm/s. It was measured again 22 seconds after the initial observation and was found to be 86 cm/s. Assuming that its acceleration was constant, find its initial velocity.
