Question

Avian Anger Management You are playing Angry Birds on your phone and you want to calculate the actual physics of the game you are playing. You have an angry bird in a sling shot that is 6m above the ground. He is launched at a 30 degree angle with respect to the horizontal and his initial velocity is 9 m/s. You need distance away on a pedestal that is 2m high. Answer the following questions... What is the tallest height from the ground that your angry bird will go? What Is the total amount of time it will take for your angry bird to hit the pig? What is the horizontal distance between the angry bird and the pig?

Explanation / Answer

Simple Projectile Shoot from a height, we have

Maximum height :

h = u2sin(30)2 /2g

h = 1.033

H = 6 + 1.033 = 7.033 m

Time in the Air

y = y0 + v0yt + ½ gt2

0 = 4 + 9sin(30)t - 4.9t2

0 = 4 + 4.5t -4.9t2

t = 1.472 seconds

Distance covered

X = v0xt

X = 9Cos(30)*1.472

X = 11.47 m
