- 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?An object is launched at 19.6 meters per second (m/s) from a 220.5-meter tall platform. The function that represents the object's height s at time t seconds after launch is s(t) = −4.9t2 + 19.6t + 220.5, where s is in meters. When does the object strike the ground?A man stands on the top of a 725 m building and drops a coin from the top of the building. How fast is the coin moving when it hits the ground? Use two different physics principles.
- A curious child stands on the top of a 607 m skyscraper and drops a coin from the top of the building. How fast is the coin moving when it hits the ground? Solve using two different physics principles and show the answer is the same.Please please answer super super fast please answer as fast as possible please answer everything correctly pleaseAn airport terminal has a moving sidewalk to speed passengers through a long corridor. Larry does not use the moving sidewalk; he takes 150 s to walk through the corridor. Curly, who simply stands on the moving sidewalk, covers the same distance in 70 s. Moe boards the sidewalk and walks along it. How long does Moe take to move through the corridor? Assume that Larry and Moe walk at the same speed.
