g = 9.81 m/s^2 , 160 feet = 48.768 metres, 21.82 mph = 9.754 metres/sec.
it passes top of building on way down at same speed so :
u = 9.754 m/s
v = ?
g = 9.81 m/s^2
s = 48.768 metres
if : v = square root of (u^2 +( 2 * g * s))
then : v = 32.434 m/s ( 72.55 mph )
The final speed of the object when it hits the ground can be calculated using the kinematic equation for motion: v^2 = u^2 + 2as, where v is the final velocity, u is the initial velocity, a is the acceleration due to gravity, and s is the distance fallen. Given that the object is thrown upwards, its initial velocity will be negative. By plugging in the values, we can solve for the final velocity.
When a ball is dropped, it starts with an initial velocity of zero. However, as it falls towards the ground, it accelerates due to gravity, causing its velocity to increase. Therefore, the velocity of the ball is non-zero as it falls towards the ground.
The vertical component of velocity for the projectile when it is fired horizontally is zero. This is because the initial velocity is entirely in the horizontal direction, and there is no initial velocity in the vertical direction. Gravity will act on the projectile, causing its vertical velocity to increase as it travels.
Building foundations have a large horizontal area of contact with the ground to distribute the weight of the structure evenly and prevent it from sinking or tilting. This helps to provide stability and support for the entire building. The larger the contact area, the more effectively the weight of the building can be spread out, reducing the risk of structural failure.
To someone on the airplane, the crate would appear to fall straight down due to its initial horizontal velocity matching the airplane's speed. To someone on the ground, the crate would follow a parabolic path because of gravity acting on it vertically while it moves horizontally due to its initial velocity.
The object will follow a parabolic path due to gravity and its horizontal speed of 45 m/s will remain constant. The time it takes to reach the ground can be calculated using kinematic equations. Its final velocity will be the vector sum of its horizontal and vertical components.
The initial cutting and breaking of soil is referred to as "ground breaking". Ground breaking ceremonies are typically conducted when building is about to commence of a structure or land development.
19.6m
The height of the building is 57.3 meters.
when we walk on the ground, our feet pushes the ground in backward direction, as a reaction ground pushes us in forward direction hence we can walk on the ground.
They should reach the ground together, since their initial vertical speed is the same, namely zero.
No. The one with higher initial speed will hit the ground first if they are both thrown straight down.
The object's initial distance above the ground The object's initial velocity
When a ball is dropped, it starts with an initial velocity of zero. However, as it falls towards the ground, it accelerates due to gravity, causing its velocity to increase. Therefore, the velocity of the ball is non-zero as it falls towards the ground.
this is because when the area of contact between the ground and the building increases the pressure exerted by the building will be less for the same force.
Newton's law of inertia applies: A body in motion tends to stay in motion, and a body at rest tends to stay at rest. This applies to earthquakes because a building or other large, fixed object is "at rest" and is not designed to be in motion. When the land vibrates and moves under a building due to an earthquake, the building has the contravening forces of inertia (the at-rest building tends to try to stay at rest) versus the ground under the building moving, and the ground doesn't play nice by moving smoothly and continuously in one direction. If it were not for inertia, the building and its contents (including people!) would simply move with the ground, and neither the building nor its contents would suffer damage.
building foundation is the base of any building which receive load from the building, resist it and transfer it to the subsoil. substructure is the structure below the ground floor bed including the ground floor bed. substructure composes of foundation, basement and ground floor bed.
i learnt it is one those presidential building and that when planes take off they divert to a different direction when heading towards it.
