1. make me 2 questions on projectile motion in the forum with complete solutions. here is my example below of what I am expecting you to answer: NOTE: Don't copy the question below make me a similar question and then solve it as you see below how they solved it. 2. Emilio is given a basketball to shoot into from a 12 m balcony, he shoots with a velocity of 6.0m/s[60° above the horizontal), and it lands into the net. What is the impact velocity of the basketball? cos 60 ziy viy vix r = (6.0m/s) cos 6 60 = 3m/s (right) sin 60 viy vi viy = (6.0m/s) sin 60 = 5.19m/s (up) a = 9.81 m/s² (down) viy = 5.19m/s (up) Ad = 12.0m (down) = vfy² = viy² + 2a A dy |vfy² = ((5.19)²) + 2(−9.81m/s²) (-12.0m) vfy = √262.376 vfy = ±16.19 m/s vfy = -16.19 a = 9.81 m/s² (down) vfy = 16.19m/s (down) A dy = 12.0m (down) vix = 3m/s vf = √√vx² +vf² vf vf = 16.46m/s 0 (3m/s)² + (16.19m/s)² = = tan - 1 = = vfy UZ 0 = tan - 1 = ( 16,10) 3 0 = 79* right 79 down

Just answer 1 and 2 Questions, encode your answer in a paragraph form 1. What are the components of projectile motion? 2. Differentiate the two in terms of: presence of force of gravity, acceleration

I submitted the answer below.  My professor asked me to answer his follow up question in bold 2. Derive an expression for the distance the rocket has traveled in terms of the initial and final speeds, and its acceleration.  After you have this expression, plug in physical values from your problem to arrive at the distance the rocket has traveled.  My thought process was to express the equation in terms of Distance = Velocity x Time.  I was using the equation v = v0 + at to rearrange to fit in the distance equation, but when I plug in my known values I do not get 91m.  Am I using the wrong equation?   Thanks SOLVED PROBLEM A rocket blasts off and moves straight upward from the launch pad with constant acceleration. After 2.8 s the rocket is at a height of 91 m. (a)What are the magnitude and direction of the rocket’s acceleration? (b) What is its speed at this time? 1.Visualize the problem:   _____          I        I  height, x = 91m        I        I ----------- 2.Describe the…

NO NEED TO SHOW ANY WORK JUST FINAL ANSWER AS QUICKLY AS POSSIBLE! I read the honor code and it says that a question can have up to 3 subparts (i.e. part a, b, c and d). Question: What was the approximate acceleration, in m/s^2, during the burning of the rocket? Sub questions: a. At what time, in seconds, does the rocket reach its maximum height?  b. What is the velocity of the rocket, in m/s, just as it reaches its maximum height? c. What is the maximum altitude, in meters, reached by the rocket? d. What is tf?

MOTION IN TWO DIMENSIONS Choose the best answer for each of the following questions. Mark your answers on the answer sheet provided by your teacher. Use the figure below to answer problems 1 and 2. 3. In a penalty kick, a soccer player kicks the ball from ground level with an initial velocity of 25.0 m/s, 20.0° above the horizontal. Assume that air resistance is negligible. What is the maximum height, ymax, of the soccer ball? A 0.51 m В 3.2 m C 3.7 m D 8.6 m 4. What is the flight time of the soccer ball in the previous problem? 1. The diagram shows the trajectory of a ball that is thrown horizontally from the top of a building. The ball's vertical and horizontal velocity vectors, along with the resultant vectors, are also indicated. If the ball takes 3.0 s to reach the ground, what is the ball's vertical speed by the time it reaches the ground? A 0.76 s В 0.87s C 1.3 s D 1.7 s A 9.8 m/s В 29 m/s C 58 m/s D 60 m/s 2. If the ball's initial horizontal velocity is 1.9 m/s, how far from…

A force of P = 50 N is applied to the 200-kg handcart. Determine the reactions at both the wheels at A and both the wheels at B. Also, what is the acceleration of the cart? The mass center of the cart is at G. Neglect the mass of wheels. Hint: 1.You need to apply the methods discussed on the kinetics of rigid bodie in plane motio. 2. The handcart does not rotate and just has translation motion in horizontal direction. 60° 0.5 m 0.2 m 0.3 m 0.2 m-- EDATE II
