Question

A particle is projected from level ground . assuming projection point as origin ,x-axis along horizontal and y-axis vertical . if particle moves in x-y plane and its path is given by y= ax-bx² . where a,b are positive constants . then match the physical quantities given with the values given .(g is acceleration due to gravity). 

a) horz. component of velocity.                                                                          i)a/b.

b)time of flight .                                                                                                ii)a²/4b.

c)max. height .                                                                                                 iii) (g/2b)^1/2.

d)horz. range .                                                                                                  iv)(2a²/bg)^1/2.
