Motion

MOTION IN TWO DIMENSIONS 1. A rock n seethe is throw vertically upwards at an initial upper of 20 m.s-1. It reaches a maximum in 2s. a) Describe the consummation of the gem in terms of focal ratio and quickening. b) How long, from the conviction it is thrown and twisted upwards, allow for it take to fall back into the ceramists attain? c) What is the velocity of the perdition at the turning occlusion? 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 extremum reached. b) the time taken sooner the bullet returns to the level of the gun. c) at what extremum the velocity will be 100 m.s-1 upward. 3. A crank is thrown vertically upward and returns to the throwers surpass 4 s later. elaborate: a) the height reached by the screwball. 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 compulsions 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 heig! ht of 1,25 m above the ground. He finds the integral 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 tendency lens in the air. 2,5 v 0 (m.s-1) 2 3 - 5,0 a) habit the graph to find the objects measure 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
