Question

An egg is thrown nearly vertically upward from a point near the cornice of a tall building. It just misses the cornice on the way down and passes a point a distance 33.0 m below its starting point at a time 5.00 s after it leaves the thrower's hand. Air resistance may be ignored. Part A What is the initial speed of the egg? v=...........m/s Part B How high does it rise above its starting point? h=.............m Part C What is the magnitude of its velocity at the highest point? v=............m/s Part D What is the magnitude of its acceleration at the highest point? a=..............m/s^2 Part E What is the direction of its acceleration at the highest point? 1. up or 2. down

Explanation / Answer

An egg is thrown nearly vertically upward from a point near the cornice of a tall building. It just misses the cornice on the way down and passes a point a distance 50.0 { m m} below its starting point at a time 5.00 { m s} after it leaves the thrower's hand. Air resistance may be ignored." -What is the initial speed of the egg? -How high does it rise above it's starting point? -What is the magnitutde of acceleration and velocity at the highest point? Given: d= -50.0m, t=5.00s Note: a= -g = -9.81m/s² So the motion equation is given by: d = vt-½gt² Solving for initial velocity v gives: v = (d+½gt²)/t = 14.5m/s (32mph) Max height is given by: d = v²/2g = 11m
