The Washington Monument is the world's tallest obelisk at 555 feet. Suppose a penny is dropped from the observation deck from a height of 500 feet. (Let t represent the number of seconds after the penny is dropped.) (a) If the acceleration due to gravity near the surface of the earth is −32 feet per second per second and the velocity of the penny is 0 when it is dropped, write the function for the model for the velocity, v,...

From the roof of the Empire State Building, you throw a coin up in the air and then watch it fall down, down, down to the street. The height of the coin (in feet) after tt seconds is given by h(t)=-16t^2+100t+1250h(t)=−16t2+100t+1250. After 12.512.5 seconds, the coin hits the street. How fast is the coin moving when it hits the street?
