More people end up in U.S. emergency rooms because of fall-related injuries than from any other cause. At what speed v would someone hit the ground who accidentally steps off the top rung of a 8.00 ft tall stepladder? (That step is usually embossed with the phrase "Warning! Do not stand on this step.") Ignore the effects of air resistance. Let the +y direction point vertically upward and the origin be on the ground.

Review Concept Simulation 2.3 before attempting this problem. At the beginning of a basketball game, a referee tosses the ball straight up with a speed of 7.94 m/s. A player cannot touch the ball until after it reaches its maximum height and begins to fall down. What is the minimum time that a player must wait before touching the ball? Number Units
A ball is thrown upward with an initial velocity of 11 m/s. The approximate value of g = 10 m/s2. Take the upward direction to be positive. What is the magnitude and the direction of the velocity of the ball 1 second after it is thrown? The magnitude of the velocity is ____m/s, and the motion is A) Upward B) Downward
A "happy ball" was dropped from an initial height of 1m as it bounced back up to a maximum height of .58 meters. When a "sad ball" was dropped from an initial height of 1m, the ball didnt bounce. Both balls have a mass of 9.5 grams. Can you please help me calculate the velocity of the "happy ball" just before and after hitting the ground using kinematics equations? Thank you in advance.
A model rocket is launched from the ground at rest. The acceleration of the rocket is ?⃗ = 90 ?̂ ? ? 2 .

A ball is thrown straight up with enough speed so that it is in the air for several seconds. Assume the positive direction is upwards. Part A - What is the velocity of the ball when it reaches its highest point Part B - What is its velocity 0.70s before it reaches its highest point? Part C - What is the change in its velocity, v, during this 0.70s interval? Part D - What is its velocity 0.70s after it reaches its highest point? Part E - What is the change in velocity, v, during this 0.70s interval? Part F - What is the change in velocity, v, during the 1.4s interval from 0.70s before the highest point is 0.70s after the highest point? (Caution: we are talking about velocity not speed) Part G - What is the acceleration of the ball during any of these time interavals and at the moment the ball has zero velocity?
Playing jackstone as a kid, you discovered that there is a certain time before the rubber ball falls and you took advantage of this when picking up the stars on the floor. If you threw the ball 2.56m/s up into the air, how fast will it be moving at a height of 11.35cm? How much time has elapsed upon reaching this height? Use GRESA and show illustration
