A cannonball is fired horizontally from the top of a cliff. The cannon is at height H = 100m above ground level, and the ball is fired with initial horizontal speed v0=0. Assume acceleration due to gravity to be g = 9.80 m/s2. a)Assume that the cannon is fired at time t=0 and that the cannonball hits the ground at time tg. What is the y position of the cannonball at the time tg/2? b) Given that the projectile lands...

A cannonball is fired towards a cliff with an initial velocity of 300 m/s at an angle of 55º above the horizontal. It explodes 42 seconds later. If we assume that our reference (0,0) is the cannon that fired it, calculate the coordinates (x, y) at which the cannon hits the cliff. Hint: Calculate the range of the projectile in 42 seconds and the height it has in that time
