an object is dropped from the top of building. how fast is it moving after 5s?...
An object is dropped from the top of a tall building. How far does it fall during the fifth and sixth seconds?
An object is dropped from the top of a building. It hits the ground with a speed of 40 m/s. a) How high is the building? b) How long was the object in the air? Kinematics (motion in a straight line with constant acceleration): xo+ vot +at2 vvo + at v2 v+2a(x -x.) dx dv 12 = a= dt dt Kinematics (motion in a straight line with no-constant acceleration): C. a dt v dt v= Vo t o x xo...
A ball is dropped from the top of a 68 m building. How long does it take for the ball to hit the ground? In the previous problem, what is the speed of the object the instant before it hits the ground?
An object, m = 2 kg, is dropped from the top of a building whose height is h=20 m above the ground. Assume that g=9.8m/s2 What is its gravitational potential energy with respect to the ground?
Use kinematic equations. A rock is dropped off of a very tall building. How fast is it going after it has fallen 13.4 m? Number Units How far has it fallen after a time of 2.84 s? Number Units
A ball is dropped from rest from the top of a building. Two motion detectors which are positioned outside of two different windows, one above the other, record the velocities of -15.5 m/s and -17.2 m/s as the ball goes past them. (no air resistance) a. How far apart are the motion sensors mounted? b. How far from the top motion sensor is the top of the building where the ball was released? c. If the second motion sensor can...
An object dropped from restfrom the top of a tall building falls y=16t^2 feet in the first t seconds.Find the speed of the object at t=3 seconds and confirmalgebraically. The answer is 96 feet/sec but how do i figure it out? cans omeone show me steps? thanks
from the edge of the roof of a building. The object reaches the ground being dropped. Determine the height of the building. [Take g-9.8m/'s) 2. An object is dropped 2. 5 seconds after
an object having a mass of 150 kg is dropped from the top of a cliff that is 100 m high. find its potential and kinetic energy after it has fallen 25 meters. JAn object having a mass of 1 kg is dropped from the top of that is 100m high. Find its potential and kinetic energy after it has fallen 25 meters
A ball is dropped from the top of a building on Earth. It takes 1.75 s to reach the ground, 15.0 m below. Calculate the acceleration due to gravity assuming air is negligible. What will happen to the value of g if the mass of the ball is decreased?
