Homework Answers
All of them have the same displacement which is the height of the building
Now v'2 = u'2 + 2as
[ I have used v' and u' because initial velocities are given in terms of symbol v which is just an arbitrary velocity]
So the one with highest u(initial velocity) will have highest v(final velocity)
So the second object having initial velocity 2v will have highest speed when it hits the ground

Three identical balls are thrown from the top of a building, all with the same initial speed
Three identical balls are thrown from the top of a building, all with the same initial speed. The first is thrown horizontally, the second at some angle above the horizontal, and the third at some angle below the horizontal. Neglecting air resistance, rank the speeds of the balls at the instant each hits the ground.

(AYK-2 modified) Two identical stones are thrown from the top of a building, both with and then again without air resistance. Stone 1 is thrown straight up, and stone 2 is thrown straight down with the same initial speed as stone 1. Which of the following statements are true (select all which apply)? □ without air resistance, stone I will hit the ground with a faster speed than stone 2 when it hits the ground. without air resistance, stone I...
A ball is thrown horizontally from the top of a 95 m building and lands 110 m from the base of the building.
A ball is thrown horizontally from the top of a 95 m building and lands 110 m from the base of the building. Ignore air resistance, and use a coordinate system whose origin is at the top of the building, with positive y upwards and positive x in the direction of the throw. Part (a) How long is the ball in the air in seconds? Part (b) what must have been the initial horizontal component of the velocity, in meters per second? Part(c)...

A ball is thrown horizontally from the top of a 60.0-m building and lands 110.0 m from the base of the building. Ignore air resistance. (a) How long is the ball in the air? (b) What must have been the initial horizontal component of the velocity? (c) What is the vertical component of the velocity just before the ball hits the ground? (d) What is the velocity (including both the horizontal and vertical components) of the ball just before it...

Three small metal balls are thrown at different speeds off the top
of a building to hit the ground 25m below. Sphere A is thrown
directly downward at 10m/s, while Sphere B is dropped from rest.
Sphere C is thrown upwards at 5m/s. Ignore the effects of air
resistance.
Calculate the time for each sphere to hit the ground below.

QUESTION 5 Alice and Tom dive from an overhand into the lake below. Tom simply drops straight down from the edge, but Alice gets a running start and dives horizontally with an initial speed of 25 m/s. Neither experiences significant air resistance. Which of the following is true about their speeds when they each hit the water? O They will have the same speed. Alice's speed is greater than Tom's OAlice's speed will be exactly 9.8 m/s less than Tom's...
