Assuming that your units of velocity are in units/second
Acceleration = (velocity 2 - velocity 1) / time
Acceleration = (4.9 - 0) / 3
Acceleration =1.63
*With correct significant figures the answer is 2

A rock dropped on the moon will increase its speed from 0 ms its starting speed when first dropped to 4.9 ms in about 3 seconds What value do you calculate for the magnitude of the acceleration o?
1.63 m/s2
Does two stones have the same acceleration if one is thrown upward from a roof and the identical one is dropped from there?
no because the higher it gets the speed increases and its do not does.
What would be the change in velocity for a 10 gram object dropped from the roof of a 20 meter building if it takes 2 seconds to reach the ground Hint acceleration due to gravity is 98 ms²?
In two seconds of fall, the speed increases 19.6 meters (64.4 feet) per second. The magnitude of velocity increases by that amount, while the direction of velocity doesn't change.
If a rock dropped on the Moon increases speed from 0 m per s to 8.15 m per s in about 5 seconds What would be the gravitational acceleration?
The gravitational acceleration would be the change in velocity divide by the time required. For this example 8.15 m/sec divided by 5 seconds yields 1.63 m/s2. (The actual average lunar gravity is estimated at 1.622 m/sec2.)
A rock dropped on the moon will increase its speed from 0 ms to 4.9 ms in about 3 seconds. What value do you calculate for the magnitude of the acceleration of gravity on the moon?
Acceleration = (change in speed) divided by (time for the change)= (4.9) / 3 = 1.63 m/s2(rounded)
WHEN A BALL IS DRoPPED FROM A height its speed increases why?
Acceleration due to the force of gravity.
A rock dropped on the moon will increase its speed from 0 ms its starting speed when first dropped to 4.9 ms in about 3 seconds What value do you calculate for the magnitude of the acceleration o?
1.63 m/s2
What is the acceleration of a full bottle of water dropped from adesk?
The acceleration of a bottle of water dropped from a desk is approximately 9.81 m/s^2, which is the acceleration due to gravity. This means that the bottle's speed increases by 9.81 meters per second every second it falls.
What is the amount by which the speed increases in one second?
It is the acceleration.
A rock dropped on the moon will increase its speed from 0 its starting speed to 8.15 in about 5 seconds If you were standing on the moon measuring the rock's motion what would you measure?
You would observe the rock falling from rest and accelerating to a speed of 8.15 m/s in about 5 seconds due to the moon's gravity. This motion can be described using equations of motion, such as the equations of uniformly accelerated motion.
Does two stones have the same acceleration if one is thrown upward from a roof and the identical one is dropped from there?
no because the higher it gets the speed increases and its do not does.
What is the the amount by which the speed increases in one second called?
It is the acceleration.
How does a change in speed affect acceleration?
Acceleration is directly proportional to the change in speed. If the speed increases, acceleration is positive. If the speed decreases, acceleration is negative. The magnitude of acceleration is determined by the rate at which the speed changes.
What would be the change in velocity for a 10 gram object dropped from the roof of a 20 meter building if it takes 2 seconds to reach the ground Hint acceleration due to gravity is 98 ms²?
In two seconds of fall, the speed increases 19.6 meters (64.4 feet) per second. The magnitude of velocity increases by that amount, while the direction of velocity doesn't change.
Why speed increases if its acceleration decreases?
stamina
What is the acceleration if the velocity increases by eighty meters per second in twenty seconds?
Average acceleration = (change in speed) divided by (time for the change)= (80) / (20) = 4 meters per second2
If a rock dropped on the Moon increases speed from 0 m per s to 8.15 m per s in about 5 seconds What would be the gravitational acceleration?
The gravitational acceleration would be the change in velocity divide by the time required. For this example 8.15 m/sec divided by 5 seconds yields 1.63 m/s2. (The actual average lunar gravity is estimated at 1.622 m/sec2.)
