- We are standing on the top of a 1040 feet tall building and launch a small object upward. The object's height, measured in feet, after t seconds is h(t) = 16t? + 128t + 1040. A) What is the object initial velocity? ft/second B) What is the highest point that the object reaches? feetA student standing on the ground throws a ball straight up. The ball leaves the student's hand with a speed of 11.0 m/sm/s when the hand is 2.10 mm above the ground How long is the ball in the air before it hits the ground? (The student moves her hand out of the way.)An apple is launched directly upward at 64 feet per second from a platform 80 feet high. The equation for this apple's height h at time t seconds after launch is h(t)= -16t2+64t+80. What is the height of the apple after 3 seconds?
- The height (in meters) of a projectile shot vertically upward from a point 4 m above ground level with an initial velocity of 25.5 m/s is h = 4 + 25.5t − 4.9t2 after t seconds. When does it hit the ground and at what velocity does it hit the groundA rocket is fired upward from some initial distance above the ground. It’s height (in feet), h, above the ground t seconds after it is fired is given by: h(t) = -16^2 + 96t +112 What’s the rockets maximum height? :____ft How long does it take for the rocket to reach its maximum height? :___? After it’s fired, the rocket reaches the ground at t= ___secondsA helicopter is ascending vertically with a speed of 5.38 m/sm/s . At a height of 125 mm above the Earth, a package is dropped from the helicopter. How much time does it take for the package to reach the ground?
- At a time t seconds, after it is thrown up in the air, a tomato is at a height (in meters) of f(t)=−4.9t^2+50t+3 m. How long is the tomato in the air?A ball is launched straight upwards starting at a height of 0.47 ×× 0.06 m. If the ball reaches a maximum height of 4.1 ×× 0.05 m, with what speed was the ball launched?A helicopter starts ascending in the sky from the ground and its position is given by y = 5t^2 + 10t. After 10 seconds, a package is dropped out from the helicopter. What is the velocity of the package when it descends to a height of 10 m above the ground.
- A rock is tossed from the top of a building at an angle of 35° above the horizontal with an initial speed of 10 m/s. The rock lands on the ground 2.7 s after it is tossed. What is the height of the building (in m)?A watermelon is dropped from the edge of the roof of a building and falls to the ground. You are standing on the sidewalk and see the watermelon falling when it is 30.0 mm above the ground. Then 1.50 ss after you first spot it, the watermelon lands at your feet. Neglect air resistance. What is the height of the building?A bird is flying due east. Its distance from a tall building is given by x(t)=28.0 m+(12.4 m/s)t-(0.0450 m/s^3)t^3.
