Answer:
d=75 m
Explanation:
The horizontal launching speed is, v = 30 m/s
The vertical distance above the ground is= h m
The time of flight t= 2.5 s
The formula for free fall to apply here is:
h=1/2 *g * t² where g is acceleration due to gravity = -9.8 m/s² and t=2.5 s
Finding h, as ;
h= 1/2 * -9.8 * 2.5² = 30.63 m
Applying the formula for range (distance d)
R= v * t
R= 30 *2.5 =75 m
The range is 75 meters.
