Answer :
The vertical height of the helicopter 30.625m
How do you find height with horizontal velocity and time?
The equation for expressing horizontal distance is x = V × t.
y = - g ×, t²/2 where g is the acceleration of gravity and h is a height, is the equation for vertical distance from the ground.
Describe the concept of projectile motion?
An object that is fired into the air and travels in that direction is called a projectile. After the force that propels an object, gravity is the sole force an object encounters. The projectile's path is the name for the object's trajectory.
Horizontal distance can be expressed as,
x = V × t
x = 80 × 2.5
x = 200
Vertical distance from the ground,
y = -g × t²/2
y = -9.8 × (2.5)²/2
y = -9.8 × 6.25/2
y = 30.625m
