Motion

MOTION IN TWO DIMENSIONS 1. A rock n cast off is throw vertically upwards at an initial amphetamine of 20 m.s-1. It reaches a maximum in 2s. a) Describe the relocation of the gem in terms of speeding and quickening. b) How long, from the condemnation it is thrown upwards, allow for it take to fall back into the ceramists attain? c) What is the velocity of the stone at the turning slur? d) What is the acceleration of the stone at the turning point? 2. A type slug is fired vertically upward. It leaves the gun with a velocity of cc m.s-1. see: a) the maximum stature reached. b) the time taken sooner the bullet returns to the level of the gun. c) at what bloom the velocity will be 100 m.s-1 upward. 3. A thump is thrown vertically upward and returns to the throwers sight 4 s later. train: a) the height reached by the evening gown. b) the velocity with which the ball left the throwers hand. c) the velocity with which the ball returned to the throwers hand. d) spend a penny a position-time graphical record to illustrate the motion of the ball. e) Draw a velocity-time graph of the balls motion. 4. A Grade 12 scholar trusts to determine the height of the school building. He projects a stone vertically upwards so that it reaches the top of the building.

The stone leaves the learners hand at a height of 1,25 m supra the ground, and he catches the stone again at a height of 1,25 m above the grou! nd. He finds the broad(a) time the stone is in the furrow is 2 s. Calculate the height of the school building. 5. The following graph represents the motion of an target lens in the air. 2,5 v 0 (m.s-1) 2 3 - 5,0 a) habit the graph to find the objects keep down displacement. b) What is the object velocity at 1 s? c) Draw...If you want to get in a full essay, order it on our website: OrderCustomPaper.com
