16. A window washer accidentally drops a bucket from the top of a 400 foot building....
A window-washer working H meters up on a skyscraper accidentally lets go off a tool while moving it sideways (i.e. horizontally) at v_0 m/s. At what angle theta (with the window washer at the vertex off the angle), will the tool hit the ground? The "given" constants are H, v_0, g. Express your answer as theta =
The height h (in feet) of an object falling from a tall building is given by the function h(t) 400 16, where t is the time elapsed in seconds (a) After how many seconds does the object strike the ground? (b) What is the average velocity of the object from t- o until it hits the ground? (c) Find the instantaneous velocity of the object after I second ft/sec Find the instantaneous velocity of the object after 2 seconds. ft/sec...
13 Ulu 16 of 25 This The rocket reaches its maximum height at foot after seconds A toy rocket is launched from the top of a building 340 feet tall at an initial velocity of 80 feet per second. The height of the rockett seconds after launch is given by the equation - 1612 + 80++ 340 When does the rocket reach it's maximum height? What is the maximum height?
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
A projectile is launched from the top of a building to hit a target on the ground. Indicate a coordinate system. Use the following values: Yo-200 fis; h = 120 ft.; θ = 40°. 2. A 40 a) Determine the maximum height that the projectile will reach measured from the ground and the time for it to reach that height. b) The time from A to B c) The distance R in the horizontal direction
3. A baseball is projected upward form the top of 448 foot tall bulding with an initial velocity of 48 feet per second. The distance s of the baseball from the ground at any time t, in seconds, is glven by the equation s-16r2 +48t+448 How long will it take the ball to hit the ground? a. b. How high will the ball be in 6 seconds? When will the ball be 448 feet in the air? c. d. If...
4. A golf ball is struck from the top of a building. The height of the ball above the ground is given by the equation: h(t) = -5t? + 20t + 60, where his in meters and t in seconds. a) Determine the average rate of change (average velocity) over the interval 35156 seconds. b) Determine the instantaneous rate of change (instantaneous velocity) at t = 3 seconds. Use at least four decimal place accuracy in your calculations.
Need help please A projectile is lunched from the top of a building with 30 degree angle below the horizon with the velocity of 40m/s. If it reaches the ground after 4 seconds then, what is the height of the building? What is the velocity of the projectile when it hits the ground? How far from the top of the building will the ball reach the ground?
If a ball is thrown upward from a building 30 m tall and the ball has a vertical velocity of 25 m/s, then its approximate height above the ground t seconds later is given by h(t) = 30 + 25t - 5t^2 a. After how many seconds does the ball hit the ground? b. What is the domain of h? c. How high does the ball go?
5. A ball is dropped from rest from the top of a building of height h 100.25 m friction, find (a) How long does it take the ball to hit the ground? (b) What speed (b) What speed does the ball travel the instant before it hits the ground?
