Answer:
a
b
Explanation:
From the question we are told that
The maximum height is H = 2.70
The Range is R = 12.9 m
Generally from projectile motion we have that
Generally from trigonometric identity
So
=>
Also the maximum height is
=>
=>
=>
=>
Dividing equation 2 by (1)
=>
=>
=>
So
From equation 1
=>
Generally the vertical component of the initial velocity is mathematically evaluated as
=>
=>
Generally the time taken is mathematically represented as
=>
=>
Slightly downstream for the shortest possible time
