A cannon accelerates a 1.5 kg cannonball at 1200m/s/s. What is the force the cannon puts on the ball?

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

photocells convert light energy to electricity

thermal energy is the answer

the components of a vector are the parts of the vectors that are to each other.
