A cannonball is launched horizontally off a 45 m high castle wall with a speed of 25 m/s. What is the range of the cannonball? o In this case, you know that the vertical component is the same as if the projectile was dropped off of the cliff with no horizontal motion. So, taking up as positive, and the bottom of the cliff as zero: d = d(initial) +v(initial)t + 0.5*at^2

Unformatted text preview: 0 = 45 + 0 - 4.9t^2 t^2=45/4.9 t=3.03 Now that you know how long the projectile takes to reach the ground, now you can ±gure out how Far the projectile travels horizontally. d= 0 + 25*3.03 = 75.76 meters Another: o A cannonball is launched horizontally of a 20 m high castle wall with a speed oF 50 m/s. What is the range oF the cannonball? 100....
