A canon ball of mass 10 kg is fired from a cannon located on the edge of a cliff overlooking the sea as shown below. The cannon is 45 m above sea level. The canon ball is fired at an angle of 15° from the horizontal with an initial speed of 250 m/s. Air resistance may be ignored What horizontal distance (in km) will it travel before it falls into the sea? answer = 3.35kN What will be its speed (in m/s) as it hits the surface of the sea? answer = 252m/s please show all working with explanantions

Question

A canon ball of mass 10 kg is fired from a cannon located on the edge of a cliff
overlooking the sea as shown below. The cannon is 45 m above sea level. The
canon ball is fired at an angle of 15° from the horizontal with an initial speed of
250 m/s. Air resistance may be ignored

What horizontal distance (in km) will it travel before it falls into the sea?

answer = 3.35kN

What will be its speed (in m/s) as it hits the surface of the sea?

answer = 252m/s

please show all working with explanantions
