The height of cliff is 44.1 m .
What is the relation between height and horizontal projectile?
An item launched into space on which gravity is the only force at work is referred to as a projectile. Some well-known instances of projectile motion are throwing a ball or firing a gun's bullet. A projectile's motion may be thought of as the result of two different motions occurring at once. In the motion of a projectile, we can see one component acting horizontally without producing any acceleration and another component acting vertically while experiencing continual acceleration due to the pull of gravity. The highest vertical location along the object's flight is considered to be its greatest height. The range of the bullet is defined as its horizontal displacement. The starting velocity of the item affects the projectile's range.If v is the starting speed, g is the gravitational acceleration, and H is the highest point that may be reached in meters, then is the beginning speed's angle from the horizontal plane (radians or degrees).
Time of flight = 7.5/2.5 = 3 seconds
Taking motion along vertical,
h = 0.5gt^2 = 0.5 x 9.8 x 3 x3 = 44.1m
