c) How long is the cat in the air for?
d) What is the maximum height?
e) What is the range of the cat?
4. After landing safely on the target the cat tries another projectile apparatus. This time the cat is
shot out of a cannon over a 30 m high wall. The cat is launched at an angle of 55°0 and can be
assumed to be at ground level during launch. With what speed (in km/h) does it have to be
launched to make it approximately 5 m over the wall if the wall is 250 m from the cannon?
