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 rocket is fired upward from some initial distance above the ground. Its height in feet, h,above the ground, t seconds after it is fired, is given by h= -16t^2+32t+3584. What is the rocket's maximum height? ___ ft How long does it take for the rocket to reach its maximum height? t= ___sec After it is fired, the rocket reaches the ground at t= ___ sec.
A model rocket is launches upward with an initial velocity of 160 feet per second. The height, in feet, of the rocket t seconds after the launch is given by h=-16t^2+160t. How many seconds after the launch will the rocket be 290 feet above the ground? Round to the nearest tenth of a second.
A cylinder is dropped from rest at a height of 3.71 m above the ground. How long after it is release does the cylinder reach the ground (in seconds)? What is the instantaneous velocity of the cylinder just before it hits the ground (in m/s)?
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.)
a baseball is hit when it is 3ft above the ground It leaves the bat with initial speed of 155 ft/sec A baseball is hit when it is 3 ft above the ground. It leaves the bat with initial speed of 155 ft/sec, making an angle of 16 questions with the horizontal. Assume there is linear drag with a drag coefficient k0.31. The acceleration due to gravity is g-32 ft/sec Answer the following ( sin a)1-k-) equations for linear drag,...

If a ball is thrown upward at 96 feet per second from a height of 12 feet, the height of the ball can be modeled by S- 12+96t seconds after the ball is thrown. How long after the ball is thrown is the height 152 feet? 16t feet, where t is the number of t takes seconds for the ball to reach th (Type an integer or a simplified fraction. Use a comma to separate answers as needed.) e height...
A person on a platform above the ground throws a ball upward at 6 feet per second. It takes 3 seconds for the ball to reach the ground below the platform. Determine the platform height above the ground. Also determine the balls speed as it strikes the ground. Assume the ball was released at the level of the platform A person on a platform above the ground throws a ball upward at 6 feet per second. It takes 3 seconds...
