If an object is dropped, the time (in seconds) it takes the object to falls ft...
In a free-fall experiment, an object is dropped from a height of h = 144 feet. A camera on the ground 500 ft from the point of impact records the fall of the object (see figure). 500 ft Not down to scale (a) Find the position function that yields the height of the object at time t assuming the object is released at time t = 0. h(t) = At what time will the object reach ground level? (Round your...
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...
The height above the ground (in feet) of a stone t sec after it is dropped from a bridge 752 ft above ground is given by the polynomial 752 - 1612 a. Factor the polynomial. b. Use the factored form in part (a) to find the height of the stone 6 sec after it is dropped. a. 752 - 1612-0 b. The stone is ft above the ground 6 sec after it is dropped. Enter your answer in each of...
A 736-lb object is launched from the ground with an initial upward velocity of 60 ft/sec. The atmosphere resists the motion of the object with a force of 3 lb for each ft/sec of speed. Assuming that the only other force acting on the object is gravity, find the time it takes for the object to reach its maximum height:
Two identical objects are dropped from rest at the same time. Object A is dropped from twice the height of object B. If there is no air resistance, which statement is true? None of the answers given is true. Both objects hit the ground at the same time. Object A takes twice the time to fall as object B. Object A takes four times the time to fall as object B.
An object dropped from restfrom the top of a tall building falls y=16t^2 feet in the first t seconds.Find the speed of the object at t=3 seconds and confirmalgebraically. The answer is 96 feet/sec but how do i figure it out? cans omeone show me steps? thanks
An object is thrown in a vertical direction from the edge of the roof of a building. The height in feet s(t) of the object seconds after it is thrown is given by the function () --167 +32+ + 48. (a) State the height of the roof. (b) State the number of seconds required for the object to reach the maximum height. sec (c) State the maximum height reached by the object (d) State the time that passes before the...
An object is dropped from a tower, 1024 ft above the ground. The object's height above ground i seconds after the fall is s(t) = 1024 - 1612. Determine the velocity and acceleration of the object the moment it reaches the ground. ft/s. The velocity of the object the moment it reaches the ground is (Simplify your answer.) The acceleration of the object the moment it reaches the ground is fus2 (Simplify your answer.)
The distance s that a certain object falls from a height of 450 ft in t seconds is given by the following formula. s = 450 - 16t2 + vt Find s when t = 3 and v = -2. ft SE
