Q17 of 37 Page 22

A particle is projected in air at some angle to the horizontal, moves along parabola as shown in Fig. 4.4, where x and y indicate horizontal and vertical directions, respectively. Show in the diagram, direction of velocity and acceleration at points A, B and C.



Acceleration is only due to gravity; therefore, it will always be pointing toward ground whereas velocity will be directed tangent to path taken by particle.
