A projectile is any object that is given an initial velocity and follows a path determined by the effects of gravitational acceleration and air resistance. Projectile motion is the act of projecting an object into the air at an angle when a curved path is an object follows when thrown or propelled near the surface of the earth.For example: a thrown football‚ an object dropped from an airplane‚ or a bullet shot from a gun.Projectile motion may only be used to solve mechanics problems

With reference to specific river basins examine the need for management in resolving issues resulting from their development (25) River basins need to be managed to resolve the two major issues which result from their development which include high flood risk and the conflict caused. The development of river basins such as the River Colorado‚ USA (an HIC) has led to unequal water distribution and many environmental problems downstream due to lack of scientific knowledge‚ which has caused conflict

a bridge at a height of 176.4 m over a river. After 2 s‚ a second ball is thrown straight downwards. What should be the initial velocity of the second ball so that both hit the water simultaneously ? 1) 2.45 ms-1 2) 49 ms-1 3) 14.5 ms-1 4) 24.5 ms-1 3. Which of the following are true ? 1. A body having constant speed can have varying velocity. 2. Position time graphs for two objects with zero relative velocity are parallel. 3. The numerical ratio of velocity to speed of an object can never be more

biggest one. This real case now can be simplified as 1-dimensional motion in the experiments. During the lab‚ the Motion Lab&VideoRECOREDER was used to record the motion of the cart. After that‚ the accelerations were gained by calculating the slope of Velocity VS. Time graph. The accelerations and the relationship among them in every stage are gained from the graph. Prediction It was predicted that the acceleration would be a constant‚ as long as the angle‚ θ‚ between the track and the desk did not

Lab Exercise 2: Acceleration A. Objective This experiment will provide data to calculate the acceleration of a marble as it rolls down an incline plane over measured periods of time. To do this‚ the marble’s velocity will be determined and then its acceleration. 1. What is the distance between two marks in your inclined plan? -50cm 2. What is the angle of your inclined plan with respect the horizontal? -16degrees 3. Newton’s first law says a body at rest will remain at rest unless

September 2017 Reading Response 2 Two Ways to See a River 1. Twain uses analogies in this short piece. In the first paragraph Twain says.” A broad expanse of the river turned to blood; in the middle distance the red hue brightened into gold…” (1). Twain is comparing the way the river shined to blood because they both are red. Using analogies puts imagery into the readers head of how the scene looked. If Twain was just to compare this river to another river that he had seen it doesn’t put images in your
