A ball is thrown vertically upward. After t seconds its height h (in feet) is h(t)=68t-16t^2. What is the maximum height the ball will reach? If ball is thrown upward with a initial velocity of 38.5 m/s and the maximum height of the ball is 74.1 meter...
A rock is thrown off of a 100-foot cliff with an upward velocity of 45 m/s. As a result, its height after t seconds is given by the formula: h(t)=100+45t-4.9t2 What is its height after 3 seconds? W A b...
A ball is thrown upward from a height of 880 feet above the ground, with an initial velocity of 96 feet per second. From physics, it is known that the velocity at time t is v(t) = 96 - 32t feet per second. How high will the ball go?
A ball is thrown upward from the top of a cliff 12 m high at a velocity of 2.8 m/s. Find the maximum height and when it is attained. How long did it take for the ball to reach the ground? A ball dropped fro...
Answer to: A ball is thrown in the air. Its height, h m, at any time t seconds is given by: h = 5t (4 - t) What is the maximum height reached by...
A ball with mass 0.19 kg is thrown upward with initial velocity 10 m/s from the roof of a building 30 m high. Neglect air resistance. (A computer algebra system is recommended. Use g = 9.8 m/s ^2 for An object of mass m = ...
