A golf ball is hit from ground level. Its path is ...

A golf ball is hit from ground level. Its path is modelled by the relation \( h = - 4.9 t ^ { 2 } + 30.6 t \) , where \( h \) is the ball's height above the ground, in metres, and \( t \) is the time, in seconds. 

a) For how long will the ball travel before it hits the ground? \( A / 3 C / 1 \) 

b) How long will it take for the ball to reach the maximum height? \( A / 1 C / 1 \) 

c) What is the maximum height of the ball? \( A / 2 C / 1\) 

Answer

a ) time = 6.245 second

b ) time = 3.2 second 

c) maximum height = 47.74 m
