A rock is thrown straight down from the Verrazano Narrows Bridge in New York City with an initial speed of 14.3 m/s. The roadway of this bridge is 70 m above the water. Take upwards to be the positive direction. a) calculate the displacement of the time t = 1.00 s. b) calculate the velocity at the time t = 1.00 s c) calculate the displacement at the time t = 1.50 d) calculate the velocity at the time t = 1.50 s e) calculate the displacement at the time t = 2.00 s f) calculate the velocity at the time t = 2.00 s g) calculate the displacement at the time t = 2.50 s h) calculate the velocity at the time t = 2.50 s
