Acceleration due to gravity = g = 10 m/s^2

Time of flight = ?

Angle of projection= θ(theta) = ?

Range attained = ?

_____________________________________

A) The Relation between Height and Total time of flight is given by,

                                             

_____________________________________

B) Total time of flight is given by,

                                             

Square root on both sides,

Iassume the answer is 75 feet. inwards to outwards rather than outwards to inwards. probably be 75.hachures are stokes drawn in direction of the steepest slope. a series of short parallel lines drawn on a map to indicate topographic relief. it is actually called hachures on contour lines. the small marks in the center of the feature are called hachures.observe the picture attached
