You are on the roof of the physics building, 46.0 m above the ground. Your professor, who is 1.80 m tall, is walking alongside the building at a constant speed of 1.20 m/s. If you wish to toss an egg on your professor's head, where should the professor be when you throw the egg? Initial velocity is shown in the figure 2. 3 m/s 46.0 m u = 1、20 m/s 1.80 m
Item 19 く 190f 20 〉 You are on the roof of the physics building of your school, 46.0 m above the ground. (See the figure.) (Figure 1) Your physics professor, who is 1.80 m tall, is walking alongside the building at a constant speed of 1.20 m/s ▼ Part A If you wish to drop an egg on your professor's head, at what horizontal distance should the professor be when you release the egg, assuming that the egg encounters...

You are walking to your physics class at speed 1.1 m/s with respect to the ground. Your friend leaves 2.0 min after you and is walking at speed 1.4 m/s in the same direction. How far does your friend travel before she catches up with you? Express your answer with the appropriate units.
As a science project, you drop a watermelon off the top of the Empire State Building, 320 m above the sidewalk. It so happens that Superman flies by at the instant you release the watermelon. Superman is headed straight down with a speed of 36.0 m/s. How fast is the watermelon going when it passes Superman?
You drop a 2.30 kg book to a friend who stands on the ground at distance - 11.0 m below. Your friend's outstretched hands are at distance 1.40 m above the ground the figure) (a) What is the speed of the book when it reaches her hands? (b) If we substituted a second book with twice the mass, what would its speed be when it reaches her hands? (c) IF, instead, the book were thrown down with initial speed 7.20...
You drop a 1.70 kg book to a friend who stands on the ground at distance D = 12.4 m below with outstretched hands at distance d = 1.52 m above the ground. (a) What is the speed of the book when it reaches the hands? m/s (b) If we substituted a second book with twice the mass, what would its speed be? m/s (c) If, instead, the book were thrown down, would the answer to (a) increase, decrease, or...
You toss a ball in the air from a height of 0.75 m above the ground. Later, you drop an identical ball from the same height. Will the first ball be moving faster, slower, or with the same speed as the second right before hitting the ground? Why?
While standing on a bridge 30.0 m above the ground, you drop a stone from rest. When the stone has fallen 5.00 m, you throw a second stone straight down. What initial velocity must you give the second stone if they are both to reach the ground at the same instant? Take the downward direction to be the negative direction.
PRACTICE IT Use the worked example above to help you solve this problem. A ball is thrown upward from the top of a building at an angle of 30.00 to the horizontal and with an initial speed of 19.0 m/s. The point of release is h = 46.0 m above the ground. (a) How long does it take for the ball to hit the ground? 4.183 (b) Find the ball's speed at impact. 35.532 m/s (c) Find the horizontal range...
