Consider a rubber ball freely falling from a height h equals 4.9 blank m onto a horizontal elastic plate. Assume that the duration of collision is negligible and the collision with the plate is totally elastic. Then the velocity as a function of time will be

h equals fraction numerator 1 over denominator 2 end fraction g t to the power of 2 end exponent comma blank(paraboli(c)
v equals negative g tand after the collision, v equals g t (straight line)
Collision is perfectly elastic then ball reaches to same height again and again with same velocity

A ball is thrown vertically upwards. Which of the following plots represents the speed-time graph of the ball during its flight if the air resistance is not ignored

For upward motion
Effective acceleration equals negative open parentheses g plus a close parentheses
And for downward motion
Effective acceleration equals left parenthesis g minus a right parenthesis
But both are constants. So the slope of speed-time graph will be constant

Figure shows the graphical variation of displacement with time for the case of a particle moving along a straight line. The accelerations of the particle during the intervals O A comma A B comma B C and C D are respectively

The portion O A of the graphs is convex upward. It represents negative acceleration. The portion A B represents negative acceleration. The portion A B represents that x is not changing with time. Clearly, it is a case of zero acceleration. The portion B C of the graph is concave upward. It represents positive acceleration. The portion C D is a straight line sloping upward to the right. It represents uniform velocity and hence acceleration is zero
