(Q11.a) A projectile is fired with speed v0=39m/s at angle theta0=22.62 from a plateau at elevation 90m above a broad and level plain. Determine the horizontal distance from the launch point at which the projectile lands[use g=10m/s^2]

(11.b) A projectile is fired with speed v0= 39m/s^2 at angle theta0=22.62 onto a level platform at elevation 10m above the launch point. The base of the platform lies 54m from the launch point. Determine the horizontal distance from the launch point at which the projectile lands.

(11.c) Check to ensure that the projectile clears the corner of the platform. What if the distance from the launch point to the platform was 5.4m?
