An object is launched from a cliff (h meters above the ground) at t= 0 with an initial launch speed of v0 m/s at an angle of m/s at angle of above the horizontal. at t = 1 sec, the projectile reaches its highest point. At t=5 sec, the object lands the on the ground below at the point marked with the distance among the base of the cliff and the point of impact is80 m. you may let g = 10m/sec^2
a) Find the initial horizontal velocity v ox and the initial velocity v ox of the projectile.
b) What is the initial launch speed v0 and the launch angle degree of the projectile?
c) What is the speed of the projectile at top of its trajectory?
d) What is the height h of the cliff?
e) What is the speed of the projectile at the moment of impact with the ground?
