A rock is projected vertically upward with a velocity of 58.0 m/s. How many metres will it pass over in the third second of its upward travel ?
It is decelerating over the three seconds, with
v0=initial velocity=+58 m/s
acceleration due to gravity, a = -9.81 m/s^2
time, t=3 s
Use kinematics equation:
Displacement=(v0)t+(1/2)at^2
Substitute above values to get displacement.
