(i) As a projectile thrown at an upward angle moves in its parabolic path (as shown), at what point along its path are the velocity and acceleration vectors for the projectile perpendicular to each other? (a) nowhere (b) the highest point (c) the launch point (ii) From the same choices, at what point are the velocity and acceleration vectors for the projectile parallel to each other?
In a volleyball game held in BSU, A CE student player at position X serves the ball from
a height of 1.3m from the ground, imparting it with an initial velocity at an angle of 50°
from the horizontal. He aimed the all to land at point 0, 0.5m short to an Engineering
Faculty player, thus making an ace, Incidentally the Engineering Faculty player is an
expert in mind reading. The instant the server hits the ball, Mr Engineering Faculty
started running from rest with a constant acceleration a.
A. Check whether the ball will clear the 2.42m high net. (Specify the height obtained in
meters)
B. At what horizontal distance in meters from position Y will Mr Engineering Faculty
intercept the ball, given that he intercepts it at a height of 1.6m?
C. What is the acceleration in m/s^2 of Mr. Engineering Faculty?

A projectile is to be fired from the centre of the top of a building that is 100 m tall. It will be fired at an angle of 60o to the horizontal and at a speed of 20 ms−1 . (a) Find an expression for the position vector of the projectile at time t seconds. (b) How long it will take for the projectile to hit the ground? (c) How far away from the the centre of the building will the projectile be when it hits the ground? You may neglect air resistance and you may assume there are no cross winds etc. (Make sure you show all your working.)
