An object falls from a height of 50.0m; the initial velocity is 0m/s, the acceleration is the acceleration of gravity 9.81m/s2. What's the velocity of this object at t=2s?
How long will it take to reach the ground?

1. Assume an
experiment is performed with an N-number of trials. Each trial
measures the same thing with exactly the same procedure and
measuring tools. The thing which we measured is the "time" of a
process, the trial number N is 3, the time is: "5.0s, 6.0s,
5.5s".
a.Then the "best"
value (arithmetic average) of this measurement of time is s (keep 2
significant figures);
b. the standard
deviation is s (keep 1 significant figures);
c. the random
uncertainty associated...
2. An object on the moon falls with a constant gravitational acceleration of −1.6m/s2. An astronaut drops a hammer from a height of 6m with an initial velocity of 0m/s. (a) Find the position function s(t) and the velocity function v(t) of the hammer. (b) After how many seconds will the hammer hit the ground? **Can you give me the solution step by step by using notes or videos? So I can understand
An object has an initial velocity of 40.0 m/s and is thrown horizontally at a height of 10 m. How long does it take to land on the ground? An object has an initial velocity of 40.0 m/s and is thrown horizontally off of a building with a height of 10 m. What is the distance from the object to the building when it lands? (How far from the building is the object?) A person kicks a football at an...
A red ball is thrown down with an initial speed of 1.3 m/s from a height of 26 meters above the ground. Then, 0.4 seconds after the red ball is thrown, a blue ball is thrown upward with an initial speed of 23.9 m/s, from a height of 1 meters above the ground. The force of gravity due to the earth results in the balls each having a constant downward acceleration of 9.81 m/s2. What is the speed of the...
(1 point) A stone thrown upward from the top of a 72 ft cliff at 119 ft/s eventually falls to the beach below. (For this problem take the acceleration due to gravity to be g-32 ft/s2; take upwards to be a positive direction.) (a) How long does the stone take to reach its highest point? time (include units) (b) What is its maximum height? height- include units) (c) How long before the stone hits the beach? time (include units) (d)...
Suppose an object falls from a great height on a planet where
the acceleration constant of gravity is g
= 7.29. Suppose that the resistance of
the atmosphere is proportional to the square of the speed of the
object with constant of proportionality k
= 0.36. Establish and solve an Initial
Value Problem to express the velocity of the object as a function
of time. Find the terminal velocity of the object. Graph this
function. Then express the fallen distance...
A red ball is thrown down with an initial speed of 1.2 m/s from a height of 26 meters above the ground. Then, 0.4 seconds after the red ball is thrown, a blue ball is thrown upward with an initial speed of 23.8 m/s, from a height of 1 meters above the ground. The force of gravity due to the earth results in the balls each having a constant downward acceleration of 9.81 m/s2. 1) What is the speed of...
Maria throws an apple vertically upward from a height of 1.3 m with an initial velocity of +2.9 m/s. Will the apple reach a friend in a tree house 7.0 m above the ground? The acceleration due to gravity is 9.81 m/s2. 1. No, the apple will reach 5.27136 m below the tree house 2. Yes, the apple will reach 5.27136 m above the tree house 3. No, the apple will reach 1.43117 m below the tree house 4. No,...
A blue ball is thrown upward with an initial speed of 22.8 m/s, from a height of 0.6 meters above the ground. 2.8 seconds after the blue ball is thrown, a red ball is thrown down with an initial speed of 7.7 m/s from a height of 28.2 meters above the ground. The force of gravity due to the earth results in the balls each having a constant downward acceleration of 9.81 m/s2. ) What is the speed of the...
An object is thrown downward with an initial velocity of 3.00 m / s from a height of 45.0 m. Determine the time in seconds it takes to reach the ground.
