Three objects are dropped from the top of a building. The first is thrown straight down with a velocity v, the second is thrown straight up with a velocity 2v, and the third is simply dropped. Which one f highest speed when it hits the ground? (Ignore air resistance.) The first. The third. They all have the same velocity. The second.

(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...

Six baseball throws are shown below. In each case the baseball is thrown at the same initial speed and from the same height above the ground. Assume that the effects of air resistance are negligible. Rank these throws according to the speed of the baseball the instant before it hits the ground. Rank from largest to smallest. To rank items as equivalent, overlap them.

A rock is thrown with an initial speed v0 from the top of a building at an angle θ (theta) above the horizontal. It hits the ground below after traveling a horizontal distance L. Find an expression for the height of the building. Your answer should be in terms of v0, L, θ (theta), and g, as needed. Please show all work!

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.

Can anyone explains all the answers? Two balls, A and B are thrown at the same angle above horizontal, but initial velocity of ball A is two times greater than initial velocity of ball B. Ignore air resistance. we can conclude that horizontal range covered by ball A is same as range covered by ball B twice the range covered by ball B four times the range covered by ball B. greater than horizontal range covered by ball b, but...

40. A projectile is launched from the top of a building with an initial velocity of 10.0 m/s at an angle of 42.0 below the horizontal. The building is 34.0 meters tall, and it stands on level ground. Air resistance is negligible. Calculate (a) the distance traveled horizontally by the projectile by the time it hits the ground, and (b) the magnitude and direction of the projectile's velocity at the instant it arrives at the ground.

A ball is thrown horizontally with an initial speed of 30m/s from the top of a building 45m tall. a. How far away from the building will the ball hit the ground? b. What is the horizontal component of its velocity when it hits the ground? c. Find the magnitude and direction of the velocity when it hits the ground?

PROBLEM: A ball is thrown downward from the top of a building at an angle of 30.0° below the horizontal. The point of release is 49.0 m above the ground and the ball lands 67.7 m from the base of the building. (a) How long does it take for the ball to hit the ground? (b) Find the ball's initial speed. (c) the speed and angle of the velocity vector with respect to the horizontal at impact. Neglect air resistance.
