Find the time taken until the ball hits the ground

Reference no: EM13998289

A ball is fired from a cannon straight up at a velocity of 30 ms^-1. The ball leaves the cannon at a height of 5 m that is vertically above the ground. Find the time taken until the ball hits the ground. Find the velocity of the ball when it hits the ground. If the ball had been projected at 10 ms^-1 instead of 30 ms^-1, what would its final velocity when it hits the ground have been? (Use g = 10 ms^-1.)
