Step 1

As per the question, it is given that a projectile is launched from the top of the cliff which is having a height of 100m, at an angle of 400 with the speed of 320m/s  and we have to find the time of flight of the projectile?

Step 2

Here velocity will have two components,

Vertical component

Horizontal component

Step 3

As the whole system is in under the gravity, so we will...
