- Problem 5 You are really angry at your family, and in your frustration you decide you are going to throw the pizza you bought for dinner onto the roof of your house. You are 6 meters from the house and the roof of the house is 3 meters above the ground. Assuming you toss the pizza from ground level with an initial speed of 10 m/s at an angle of 60° (above the horizontal), how far onto the roof does the pizza land? Assume the roof is flat. Give your answer to 2 significant figures.I I6 PART B A player hits a tennis ball into the air with a velocity of 10 m/s at an angle of 60° to the horizontal. i) What was the initial horizontal velocity of the ball? i) What was the initial vertical velocity of the ball? (g = 9.8 m/s) U = initial velocity: Ux initial horizontal velocity Uy = initial vertical velocity Note: Ux = Ucose Uy = Usine %3D 9MEPls help
- Current Attempt in Progress X Incorrect A marksman fires a practice round from A toward a target B. If the target diameter is 300 mm and the target center is at the same altitude as the end of the rifle barrel, determine the range of "shallow" launch angles 8 for which the round will strike the target. Neglect aerodynamic drag and assume that the round is directed along the vertical centerline of the target. (Note: The word "shallow" indicates a low-flying trajectory for the round.) 860 m/s Answers: i 0.553 1470 m °ses 0.565 BQ3. A 3.0kg cannon ball is shot from a cannon at a speed of 20m/s. The cannon is oriented50 degrees above the horizontal and the cannon’s barrel is 8.0m above the ground. Youwant to position a mat that will catch the cannon ball.a. Determine how much time the cannon ball will spend in flight.b. Draw a force diagram for three points during the cannon ball’s flight (1) while itis being shot from the cannon, (2) when it is at its maximum height, and (3) whenit is half-way between the maximum height and the mat.c. Determine the horizontal distance from the end of the barrel where you shouldplace the mat so that it will catch the ball.d. How fast is the cannon ball moving just before it hits the mat?
- unched, and ballistics is study of projectile motion. Examples of projectiles range from a golf ball in flight, to curve ball thrown by a baseball pitcher to a rocket fired into space. b) The force of gravity causes a projectile to follow a parabolic path: TRUE or FALSE? c) A ball is dropped, while another ball is thrown horizontally at the same time and from the same height. Both balls will hit the ground at the same time; TRUE or FALSE? d) Ignoring air resistance, a launched projectile moves through the air only under the force of gravity; TRUE or FALSE? Section B Instruction:Show all your steps to the final answer. 1. A tennis ball is thrown horizontally ata speed of 15 m/s.out ofFlight of a golf ball A golf ball is driven down a horizontal fairway withan initial speed of 55 m/s at an initial angle of 25° (from a tee with negligible height). Neglect all forces except gravity, and assume the ball’s trajectory lies in a plane.a. When the ball first touches the ground, how far has it traveled horizontally and how long has it been in the air?b. What is the maximum height of the ball?c. At what angles should the ball be hit to reach a green that is 300 m from the tee?Dynamics of Rigid Bodies (Projectiles) A stone is thrown from a hill at an angle of 60° with the horizontal on an initial velocity of 30 m/s. After hitting the level ground at the base of the hill, the stone has covered a horizontal distance of 150 m. How high is the hill? include FBD and complete solution
- If you can answer this question pleaseDynamics Help! If a baseball player throws a ball a horizontal distance of 100 m in 4 seconds at 45° latitude, by how much is it deflected laterally if he throws toward the east? a) Starting from the appropriate component either du/dt, dv/dt, or dw/dt find an expression for v (no numbers just the variables) b) Find an expression for y (again no numbers, find the equation c) Calculate the actual meridional deflection using the appropriate numbers given in the problem and explain or describe in words what this number means (specific direction)
