All are true false but need help on all of them thanks in advance 1)Knowing the position and velocity of a particle allows its future position to be predicted even if its acceleration is unknown. 2)Instaneous velocity is the derivative of the displacement time function. 3)If the displacement of a particle is decreasing at a constant rate its acceleration is constant. 4)For problems involving constant acceleration the mean and instantaneous velocity are the same. 5)The slope of the velocity time graph is the instantaneous acceleration.
