Problem 2. (25 points) A golfer hits a golf ball with an initial speed of 30 m/s at an angle of 35° with the ground. The ball flies over the level ground and lands at the same height from which it was hit. a) How long does it take for the ball to reach its highest point? b) What is the range of the ball? c) Find the velocity of the ball just before it hits the ground. d) After...
A ball is thrown straight up from the edge of the roof of a building. A second ball is dropped from the roof a time of 1.14 s later. You may ignore air resistance. Part A If the height of the building is 21.0 m, what must the initial speed be of the first ball if both are to hit the ground at the same time? m/s Submit Request Answer Incorrect; Try Again; 3 attempts remaining Part B Consider the...
3 -45 points SAigTrig4 1.4.085 0/3 Submissions Used Notes Ask A ball is thrown straight upward at an initial speed of vo 40 t/s. (Use the formula h--16+vot. If not possible, enter IMPOSSIBLE.) (a) When does the ball initially reach a height of 24 ft? (b) When does it reach a height of 48 t? (e) What is the greatest height reached by the ball? ft (d) When does the ball reach the highest point of its path? (e) When...
URGENT. This isn’t so much a question but rather a understanding. Can you check if my answers are correct for the following. I have attached the way it’s supposed to be done. Can you let me know if my work is correct? Problem 3. A ball is thrown with initial speed vo at an angle θ above the horizontal. a) What is the maximum height, h, that it will reach? 2. b) How fast, V, will the ball be moving...
please explain III Which of the following is the correct graphical representation for C-(A-B)? (Symbols in bold type are vectors) IIII] When a ball is thrown vertically up with some initial speed it slows down as it moves up reaches a certain maximum height, and then falls straight down. Assume no air friction. During the trajectory of the ball in the air, which one of the following is true? lal The acceleration and velocity of the ball both increase on...
A ball with a radius r and a mass m starts from rest and then rolls without slipping a distance L down a roof sloped at an angle θ. The ball comes off the roof a height H above the ground. Derive an expression for the ball’s speed v, just as it leaves the roof, in terms of g, L, and θ: A. If the ball is a solid sphere. B.If the ball is a hollow sphere. C. For each...
A ball is launched from the ground at an angle of 65∘ above the horizontal with a velocity of 22m/s. The ball hits the ground some distance away at a given speed, and bounces back up. When it does so the amplitude of both the x and y components of its velocity are half what they were. This repeats with the ball losing half of it’s speed on each bounce. a) Sketch the problem. [2 points b) Write the equation...
E.1. [14 points) A soccer ball starts from rest when it is at a vertical height yo = 3.00 m above the ground and rolls without slipping down a curved ramp, as shown in the diagram. The ball rolls off the ramp when it is at a vertical height yı = 1.25 m above the ground. Assume the soccer ball is a hollow sphere (spherical shell) of radius 12 cm and mass 450 g. Ignore all frictional losses What is...
Problem 1 (American football) For the purposes of this problem, neglect air re- sistance. Suppose that you and your friend are playing catch with a football of mass m at some distance D apart from each other, as shown in the figure below FI (a) (5 points) At first, your friend is nice and throws the ball to you exactly where you r friend throws the ball from some height H above the ground at are. Assuming you some anglefro...
PRACTICE IT Use the worked example above to help you solve this problem. A ball is thrown upward from the top of a building at an angle of 30.00 to the horizontal and with an initial speed of 19.0 m/s. The point of release is h = 46.0 m above the ground. (a) How long does it take for the ball to hit the ground? 4.183 (b) Find the ball's speed at impact. 35.532 m/s (c) Find the horizontal range...
