1) A projectile is fired with an initial speed of 51.2 m s^–1 at angle 44.5º above the horizontal on a long flat firing range. Point A is the maximum height attained by the projectile.
What is the vertical component of the velocity and location of the projectile 1.50 s after firing?

2) A ball is thrown horizontally from the top of a cliff with a speed of 40 m/s. It hits the ground after 2.0 s. What is the distance from the cliff to the point at which the ball hits the ground?

3) An aeroplane, flying in a straight line at a constant height of 500 m with a speed of 200 m s^–1, drops an object. The object takes a time t to reach the ground and travels a horizontal distance d in doing so. Taking g as 10 m s^–2 and ignoring air resistance, which one of the following gives the values of t and d?

4) The figure below shows the path of a ball leaving the ground at point X and about to hit the ground at point Z.

If air resistance is negligible, the vertical component of

5) A ball is projected horizontally from the top of a cliff on the surface of the Earth with a speed of 40 m s^–1. Assuming that there is no air resistance, what will its speed be 3.0 s later?
