Acannonball of mass 28.7 kg is shot into the air at an angle of 45 degrees with respect to horizontal. at the top of its ballistic trajectory, the cannonball suddenly explodes into two separate pieces, a smaller piece this is 1/3 the original mass, and a larger piece that is 2/3 the original mass. the smaller piece ends up landing right back at the spot where the cannonball was originally launched, 16.3 seconds after it was launched. how far from the launch site does the larger piece travel? you can neglect the effects of air resistance

Acannonball is catapulted toward a castle. the cannonball's velocity when it leaves the catapult is 40 m/s at an angle of 37° with respect to the horizontal and the cannonball is 7.0 m above the ground at this time. (a) what is the maximum height above the ground reached by the cannonball? (b) assuming the cannonball makes it over the castle walls and lands back down on the ground, at what horizontal distance from its release point will it land? (c) what are the x- and y-components of the cannonball's velocity just before it lands? the y-axis points up.

Three balls are launched from the same point high on a cliff - they all end up landing at different places on the flat ground below. the launch point is 30.0 m above the ground, and all the balls are launched with the same speed of 28.0 m/s. ball a is launched with an initial velocity that is entirely horizontal. ball b's initial velocity is directed at an angle of 43.0 degrees above the horizontal. ball c's initial velocity is directed at an angle of 22.0 degrees below the horizontal. as usual, we will neglect air resistance. use g = 9.80 \; m/s^2. rank the balls based on the speed they each have just before impact with the ground, from largest to smallest.
