(10%) Problem 5: A ball with an initial velocity of 5.5 m/s and mass 2.5 kg moves at an angle 68° above the horizontal. The ball hits a vertical wall and bounces off so that it is moving 68° above the horizontal, moving in the opposite direction with the same speed. See the figure. е 4 What was the magnitude of the impulse delivered by the wall, in kilogram meters per second? Grade Summary Deductions Potential 100% E sin cos...
If a ball is thrown upward at 49 meters per second from the top of a building that is 35 meters high, the height of the ball can be modeled by S = 35 + 49 - 4.912, where t is the number of seconds after the ball is thrown. Answer parts a through c a. Find the t-coordinate and S-coordinate of the vertex of the graph of this quadratic function. The t-coordinate of the vertex of the graph of...
a ball is thrown upward at 64 feet per second from the top of an 80 feet high building. The height of the ball can be modeled by S(t) = -16t^2 + 64t + 80(feet), where t is the number of seconds after the ball is thrown. describe the graph model
Kenneth Cukier highlighted a number of issues with predictive analytics in his Ted Talk on big data. One of those was the potential for punishment based on predictions. What is your reaction to using big data and predictive analytics in this way?
A man is at the top of a tower, and drops a ball. One second later, he throws another ball down with a speed of 20.0 m/s. They hit the ground at the same time. How high (in meters) is the tower?

Section 13.5 Gravitational Potential Energy 15. An astronaut on earth can throw a ball straight up to a height of 15 m. How high can he throw the ball on Mars?
A ball is thrown vertically upward with an initial velocity of 96 feet per second. The distance s (in feet) of the ball from the ground after t seconds is s(t)=96t-16t^2a.) at what time will the ball strike the groundb.) for what time t is the ball more than 128 feet above the ground?c.) when will the ball reach its highest peak? how high is it above the ground?
For this week, watch before class the Sherry Turkle Ted Talk video and we will discuss in class one or more of the areas below. In preparation, write a short 2-4 paragraph report that summarizes what Sherry Turkle's main point is also what is your point of view on this topic? Submit it to Moodle to be graded • Pretend empathy • "We expect more from technology and less from each other" • Never having to be alone - discuss...
A ball is thrown up 90 feet in the air. it comes down, bounces, and then rises up to a height of 81 feet. Then it falls to its second bounce, and so on. Each time it falls, it bounces back to 90% of its previous height. (a) How high does the ball rise before the 30th bounce? (Please read the question carefully. If the question read “How high does the ball rise before the second bounce?” the answer would...
