A rock is dropped from rest and falls for 3 seconds what is the acceleration?

The acceleration due to the earths gravitational field at the surface is on average about 9.8 m/s^2, or 9.8 meters per second per second. This means that every second you fall go 9.8 m/s faster. So if we ignore air-resistance we find that a rock dropped from rest will have a speed of 3s * 9.8 m/s^2 = 29,4 m/s.

A stone falls from rest how fast is it falling after 10 seconds?
Speed = (acceleration) times (time)Acceleration = gravity = 9.8 meters (32.2 feet) per second2Speed = 10g = 98 meters (322 feet) per second
What is the acceleration experienced by a car that takes 10 seconds to reach 27 meters per seconds from rest?
velocity = acceleration x time 27 = acceleration x 10 acceleration = 2.7 m/sec/sec
What is the distance covered by a freely falling object 5 seconds after it is dropped from rest?
0.7848 meter
Hits a speed of 50 m s after 5 seconds what is his rate of acceleration?
If he started out from "rest" (zero speed), then his average acceleration for the 5 seconds is50/5 = 10 meters per second2
What is the acceleration by a freely falling object 5 seconds after it is dropped from rest?
It depends if it is affected by air resistance or not. If not then all objects close to the surface of the Earth have an acceleration of 9.81ms^-2 in free fall. If it is affected by air resistance you need all sorts of more information to answer that question, like the drag coefficient of the air.

What is the average velocity of the particle from rest to 9 seconds?
The answer will depend on its acceleration.
How far will a freely falling object dropped from rest in eight seconds?
Assuming constant acceleration due to gravity, the object will fall a distance of 313.6 meters in 8 seconds. This is calculated using the formula ( d = \frac{1}{2} g t^2 ), where ( d ) is the distance fallen, ( g ) is the acceleration due to gravity (approximately 9.81 m/s(^2)), and ( t ) is the time elapsed.

Is a car accelerates from rest to 27M/S 22.9 seconds what is the average acceleration?
the acceleration of the car is 1.179m/s/s given the formula provided.

A 12 kg rock falls from rest off a cliff and hits the ground in 1.5 s What is the velocity?
The acceleration of gravity is 9.8 meters/sec2.In 1.5 seconds after it's dropped, any object is falling at (9.8 x 2) = 19.6 meters/sec.The mass of the rock makes no difference.
A constant forces of ION pushes a 10 kg box of 10 seconds If the was initially at rest what its speed after 10 seconds?
To determine the speed of the box after 10 seconds, we need to use the formula for acceleration: ( a = F / m ), where ( a ) is acceleration, ( F ) is the force, and ( m ) is the mass. Given that the force is constant and the box starts from rest, we can further use the equation for speed ( v = a * t ), where ( t ) is time. Calculate the acceleration using the force and mass, then use that acceleration to calculate the final speed after 10 seconds.
A ball is dropped from a window and takes 2 seconds to reach the ground. It starts from rest and reaches a final speed of 20 MS What is the balls acceleration?
The acceleration of the ball can be calculated using the formula: acceleration = (final velocity - initial velocity) / time. In this case, the initial velocity is 0 m/s, the final velocity is 20 m/s, and the time is 2 seconds. Therefore, the acceleration would be (20 m/s - 0 m/s) / 2 s = 10 m/s^2.
A 15kg ball and a 25kg ball are dropped from rest what will be the acceleration of the heavier ball?
Same as the 15kg ball. 9.8m/sec^2.
