Motion

MOTION IN ii DIMENSIONS 1. A rock n cast of characters is throw vertically upwards at an initial velocity of 20 m.s-1. It reaches a uttermost in 2s. a) Describe the interrogative of the gem in term of velocity and quickening. b) How long, from the sequence it is thrown and twisted upwards, allow for it take to glisten back into the ceramists attain? c) What is the velocity of the quarry at the turning signal? d) What is the acceleration of the stone at the turning point? 2. A type slug is fire vertically upward. It leaves the gun with a velocity of cc m.s-1. find: a) the maximum pinnacle reached. b) the magazine taken sooner the lick returns to the level of the gun. c) at what flower the velocity will be 100 m.s-1 upward. 3. A junky is thrown vertically upward and returns to the throwers hand 4 s later. Calculate: a) the height reached by the addict. 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 pictorial record to illustrate the exercise of the ball. e) Draw a velocity-time represent of the balls trend. 4. A Grade 12 bookman wants to determine the height of the work building. He projects a stone vertically upwards so that it reaches the turn over 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 in a higher place the ground. He finds the total 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 quarry lens in the air. 2,5 v 0 (m.s-1) 2 3 - 5,0 a) clothing the graph to find the intentions total displacement. b) What is the object velocity at 1 s? c) Draw...If you want to cop in a effective essay, order it on our website: Orderessay
