A rock is thrown straight down from the Verrazano Narrows Bridge in New York city with an initial speed of 14.7 m/s. The roadway of this bridge is 71 m above the water. Take upwards to be the positive direction.  part b) calculate the velocity at the time t = 1.00 s part c) calculate the displacement at the time t = 1.55 s part d) calculate the velocity at the time t = 1.50 s part e) calculate the displacement at the time t = 2.50 s part f)  calculate the velocity at the time t = 2.00 s part g) calculate the displacement at the time t = 2.50 s part h) calculate the velocity at the time t = 2.50 s
