An object is thrown vertically downward with an initial speed of

An object is thrown vertically downward with an initial speed of 20m/s. from the window of a tall building. The object hits the ground after 6.0s. the height of the window above the ground is: 300m 32m 200m 180m 60m A car travelling west at 20m/s turns and then travels east at 30m/s. The change in its velocity is: 10m/s east 50m/s west Zero 10m/s west 50m/s east
