This man explains everything better than my textbook does 👏🏽👏🏽👏🏽

[@clementmokwena8861]

You just saved my life bro. You explain better than this lectures who don't know anything eish 😕

[@radebecena5807]

That's why the call him the GOAT 🐐 of Eng🔥

Why are we using the vertical component to calculate the displacement instead of the horizontal component??

[@akileshramouthar7523]

Hello sir can I please ask you a question it's about angular motion?

[@mechackkaba8578]

A express train travels from north to south at 103km/h A helicopter flies over the train at 187km/h from the front. Calculate the velocity of the helicopter relative to the velocity of the train in magnitude and direction. Help me with this one I'm stuck

[@ruhaanb6]

Velocity of Helicopter with respect to the train = +Velocity of Helicopter - (-Velocity of train) = 187 + 103 = 290 km/h (Since it is going from south to north... and I assumed south to be negative)

[@benhardamakally7610]

How can I calculate the angle of projection if I only given the maximum height

[@mhanl5069]

Are you given time ? If you are then use Displacement=Horizontal Component x time then substitute values in the formula

[@benhardamakally7610]

No Just the vertical height

A rocket is launched from a cannon on the ground at an angle to hit an office 220m above the ground in a building. Determine the angle of projection necessary to hit the office.
