Why does an object dropped from a certain height have more than twice the speed of an object dropped from half the height of the previous object?

Because they undergo an acceleration. Free fall velocity is the function of a square.


What happens when an object is dropped from a helicopter?

When an object is dropped from a helicopter, it will fall due to gravity. Its speed and direction will be influenced by air resistance and any wind present. The object will accelerate until it reaches its terminal velocity, which is the maximum speed at which the air resistance equals the force of gravity.


What interval is the objects speed greatest?

The object's speed is greatest when the acceleration is highest. This typically occurs when the object is accelerating in the same direction as its motion, such as when an object is dropped and falls freely under the influence of gravity.


An object is dropped and is in free fall The speed of the falling object and the distance it falls are measured every second Which of the following is correct?

The speed stays thesame but the distance stays the same.


Speed of a dingo animal?

Dingoes have a top speed of 40 miles per hour. They can achieve this speed due to their lightweight frame, with males not weighing more than 33 pounds.


What is the instantaneous speed of an object 2 second after being dropped in a vacuum?

In a vacuum, the instantaneous speed of an object 2 seconds after being dropped would be approximately 19.6 m/s, as the acceleration due to gravity is 9.8 m/s^2 and the object would have been accelerating for 2 seconds.


Suppose an object in free fall is dropped from a building Its starting velocity is 0 Ignoring the effects of air resistance what is the speed of the object after falling 3 seconds?

The speed of the object after falling for 3 seconds in free fall is 29.4 m/s.


What happens if a large mass is dropped into something moving at constant speed?

The object that is moving at a constant speed will slow down. Its new velocity will be determined by the original constant speed along with the new combined mass of the moving object and the additional "large mass."


When an object in free fall is dropped from a building Its starting velocity is 0 ms Ignoring the effects of air resistance what is the speed in ms of the object after falling 3 seconds?

What is the speed of an object that is dropped off a cliff after 5 seconds and no air resistance with an initial speed of 0 ms?

The speed of an object dropped off a cliff after 5 seconds, neglecting air resistance, is given by the equation: v = gt, where v is the final speed, g is the acceleration due to gravity (9.8 m/s^2), and t is the time it has been falling. Plugging in the values gives v = 9.8 m/s^2 * 5 s = 49 m/s. So, the speed of the object after 5 seconds will be 49 m/s.


Will two objects that have the same mass that are dropped from two different heights meet at the same speed?

No because 'g' is irrespective of the object's mass.


Do two objects of the same mass dropped at different height have a different speed?

Yes, two objects of the same mass dropped at different heights will have different speeds when they hit the ground due to the influence of gravity. The object dropped from a higher height will have a higher speed upon impact because it had more time to accelerate while falling.
