In which graph does the particle have a constant acceleration for the entire 5 s

Question

In which graph does the particle have a constant acceleration for the entire 5 s? A ball has been thrown vertically upward. The graph shows the ball's position as a function of Which one of the following statements best describes the motion of the ball? The velocity of the ball is the same at points A, B, C, D, and E. The acceleration of the ball is 9.8 m/s2 at points A, B, D, and E and zero at point C. The acceleration of the ball is -9.8 m/s2 at points A, B, D, and E and zero at point C. The ball is the same distance above the ground at points B and D. The velocity of the ball changes continuously during its flight.

Explanation / Answer

in the 5 th question the constant acceleration represent the graph 2 is correct one because the velocity and time graph moving along straigt line the remaing graph does not represent the velocity and time does not equal

in the 6 th question 5 option is correct if moving in verticaly up wards in cause of air rsistance the velocity decreases continously in the option 1 the velocitys are not same in point C the velocity is zero

in the option 2&3 the acceleration does not zero because the acceleration is 9.8 at c

in the option 4 the same does not applicable the distance Band C is less compare to B and D
