A projectile is launched from the ground with initial speed that sin 0 = 4/5. There is a vertical cliff at a distance 160 m a 80 m. Gravitational acceleration is g = 10 m/s. (a) What is the maximum height from the groundlevel reached by the projectile? (b) What is the total time of flight? (c)How far away from the edge of the cliff doesthe ball fall (i.e., D=?)?
