A projectile of mass 6 kg was launched with a velocity of 25 ms\\\' making an angle of 50° with the horizontal, from a height of 8 m. 

a. Draw the trajectory of the projectile from the time it was launched till it hits the ground.
b. Calculate the time taken to reach the maximum height.
c. Calculate the total time of flight.
d. Calculate the range of the projectile.
e. Calculate the velocity of the projectile after 3.5 s. Mark on the diagram with letter \\\'A\\\' the probable position of the projectile after 3.5 s.
f. Calculate the total energy of the projectile.
g. What is the minimum potential energy of the projectile?
h. Determine the minimum kinetic energy of the projectile.
Calculate the maximum height of the projectile.
j. Mark on the diagram With letters \\\'B\\\' and \\\'C\\\', two points where the speed is the same. Show with arrows the directions of velocity at points \\\'B\\\' and \\\'C\\\'.

k. Calculate the speed of the projectile just before it hits the ground. State two everyday examples of projectile motion on Earth.
m. State the changes if air resistance is taken into consideration.
n. State the changes if the experiment is done on the moon.
