    ok so if an object is falling in water will upthrust still be lower than drag and weight would be the biggest force. the object is not floating.

    oh ok so in parabolic motion the velocity will not be 0 at the lowest position right like it happened in a wave? i thought that i a wave the velocity is 0 only at the highest point and not the lowest point :)

    about the 2nd mcq we are asked to tell velocity at the lowest point so why isnt it C. At C the wave should be moving downwards right? At D the wave wouldnt be moving down it wud be in the middle of its motion no? :(((
