A rocket raises vertically in such a way that, t seconds after lift-off, it is h(t)=-1/2tsquar+30t metres above the ground. a.how high is the rocket after 40 seconds. b.what is the average velocity of the rocket over the first 40 seconds of the flight between t=0 and t=40

how poistion is same as displacement in the beg5of the video

[@MathematicsTutor]

Initial value is zero. That is the reason. Hope that helps. Thanks

[@sachinrath219]

@@MathematicsTutor so by definition velocity is the rate of change of position not displacement as rate of change of displacement carries no meaning, displacement itself is the change in position.

[@MathematicsTutor]

@@sachinrath219 velocity is rate of change of displacement. The function also represents displacement as at t = 0 position is also zero. Thanks

[@sachinrath219]

@@MathematicsTutor hope displacement comes only when a body is displaced i e changes its position, velocity seems to be rate of change of position, can u verify the definition from any standard physics book, thanks

[@sachinrath219]

pl check the definition in en.m.wikipedia.org/wiki/Velocity

speeding is not in american english. Do you mean speeding up ???

[@vaibhavtyagi9515]

Speeding means accelerating
