A cannon can fire a cannonball at 20m/s. A sandpit is placed at a distance of 40m away. At what angle should the cannon be fired in order for the cannonball to land in the sand.
Assume: No air resistance Sandpit of negligible height *** Steps (To be explained on whiteboard in full) Draw a diagram First look vertically Then look horizontally Formulate final equation for angle Sub in values given and find angle
