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)

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
A rock dropped on the moon will increase its speed from 0 ms its starting speed when first dropped to 49 ms in about 3 seconds What value do you calculate for the magnitude of the acceleration o?
Acceleration = (change in speed) divided by (time for the change).From the figures given in the question, the acceleration is ( 49/3 ) = 16.33 m/sec2 .There's no way that this is happening on the moon. That acceleration is about 67% greaterthan the acceleration of gravity on the earth's surface. It should be about 83% less, or about 1.63 m/sec2.I see the problem now. The '49' in the question should be '4.9'.apex- 1.63 m/s2
Does gravitational acceleration calculate potential energy?
Gravitational potential energy describes how much energy a body has in store by virtue of having been elevated to a specific height. The formula to calculate gravitational potential energy is:.U = mgh.Where:U is the potential energym is the mass of the objectg is the acceleration due to gravity, andh is the height the object will fall if dropped.
What is A ball is dropped from 5 m height What is its acceleration when it is at a height of 2.5 m?
Its acceleration is always the same - the acceleration of gravity at 32 ft/sec/sec - no matter what distance it is during drop, until it hits the ground.
If a rock is dropped and it's speed increases from 0 to 4.9 in about 3 seconds. what is the acceleration?
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

Why velocity is non zero when ball dropped to the ground?
The initial velocity of a dropped ball is zero in the y (up-down) direction. After it is dropped gravity causes an acceleration, which causes the velocity to increase. F = ma, The acceleration due to gravity creates a force on the mass of the ball.
A ball is dropped and a ball of similar mass is fired which has greater acceleration?
If we disregard air resistance; they both have identical acceleration under gravity. If we take air resistance into account, then the mass that is fired will be de-accelerating slightly, so if you calculate the overall acceleration it will be slightly lower than the mass that is dropped.
What is the acceleration of a dropped object?
9.8 m/s/s
How do you calculate the velocity and acceleration of falling objects?
As usual when we talk about falling objects, we have to ignore air resistance,because its effects depend on the size, shape, and composition of the objectthat's falling, as well as the temperature, pressure, humidity, and wind-speedof the local air, and we have none of that information. So we must simply treatthe whole subject as if the only effects on the falling object are those that arethe result of gravity.Velocity:-- The direction of the velocity vector is down.-- The magnitude of the velocity vector (called "speed") is(initial downward speed when dropped or tossed) plus (acceleration x time spent falling).Acceleration:-- Direction of the acceleration vector is down.-- Magnitude of the acceleration vector depends on what planet you're on or near,but is always the same as long as you stay there, and doesn't need to be calculated.In the case of Earth, it's 9.8 meters (32.2 ft) per second2 .

A ball is dropped and its motion recorded It is found that the increase in speed is uniform for each second it falls Which inference do these observations support?
If the increase in speed is uniform, this means that the slope of the function of speed over time is constant. This means that acceleration is constant.
If air resistance can be neglected how does the acceleration of a ball that has been tossed straight upward compare with its acceleration if simply dropped?
The acceleration is the same, which is the acceleration due to gravity. About 10m/s^2
A bullet dropped versus a bullet fired from a gun which has greater acceleration?
The bullet fired from a gun has greater horizontal acceleration. For vertical acceleration, they are both the same.
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?
That works out at an acceleration of 1.63 m/s2(Presumably you meant 8.15 meters per second.)You would measure how far the rock dropped in 5 seconds. Then you could work out the final speed (or acceleration) from the "equations of motion".
WHEN A BALL IS DRoPPED FROM A height its speed increases why?
Acceleration due to the force of gravity.
