Hey, may i know how can i find the center of gravity in an inclined plane?? is it using the formulae total length divide by 2?? But isnt that for horizontal only and not inclined?? help me pls im confused!! sorry, it is an inclined rod...i mean it is like a rod leans against a smooth vertical...

A golf ball leaves the ground with a speed of 30ms^-1 of an angle of 30 degree above the horizontal. Find 1) the horizontal and vertical component of initial velocity 2) the velocity at the height of 5m above the ground 3) the max height and the coordinate at that point 4) the time of flight...

A ball is rolled horizontally on top of a 35m high building. Then it fell to the ground 80m away from the foot of the building. Determine : 1) Time of flight 2) Initial velocity of the ball 3) Velocity just before the ball hits the ground
