- The ball land 71.5m away from the base of the cliff.
- The time taken by the ball in the air is 11.79secs
- The maximum height (above the cliff’s edge) that the cannon ball attains is 170.58m
a) To get how far from the base of the cliff does the ball land, we will use the SOH CAH TOA identity.
This shows that the ball land 71.5m away from the base of the cliff.
b) The time the ball used in the air is the time of flight and it is expressed as:
Hence the time taken by the ball in the air is 11.79secs
c) The formula for calculating the maximum height is expressed as:
Hence the maximum height (above the cliff’s edge) that the cannonball attains is 170.58m.

We know that one wall side is 5m.
To find the area of one wall, we do 5²=25m²
We know there is 4 walls. So we have to find total area of all four walls.
Which is 25×4=100m²
To find the total cost of white washing the room, we have to do:
100(total area)×23(cost per m²)=$2300
So the total cost of the area is $2300
