A physics book of unknown mass is dropped 4.85 m What speed does the book have just before it hits the ground?
Acceleration of an object, to a point is constant. The SIMPLE answer is beloow. Accelerating object will change their velocity so... 0 second = 0 velocity 1 second = 4 m/s 2 seconds = 8 m/s 3 seconds = 12 m/s and so on until terminal velocity... so the simple answer to your question is... just over 1 second. To get an exact answer will take more excating calculation as this is a curve.

What form of energy did the ball have before it was dropped?
The ball had potential energy before it was dropped. This potential energy was due to its position above the ground.
Which has more kinetic energy a ball dropped from a height of 2m or a same ball dropped at 4m which has more kinetic energy just before it hits the ground?
The ball dropped from 4m height has more kinetic energy just before it hits the ground because it has a higher velocity due to falling from a greater height. Kinetic energy is directly proportional to both mass and the square of velocity, so the ball dropped from 4m height will have more kinetic energy than the one dropped from 2m height.
Is an atomic bomb detonated or dropped?
An atomic bomb is usually dropped from an aircraft before detonation. The bomb is released from the aircraft, allowing it to fall toward the target area where it explodes upon impact with the ground.
Why dropped objects hit the ground at the same time?
Dropped objects hit the ground at the same time (as long as they're dropped from the same height) because the acceleration of gravity is constant. On earth, it's 9.8 meters per second (32.2 feet per second) every second.
When Rae dropped a bowling ball from a height of 8 meters At which distance above the ground was the ball most likely moving at the greatest speed?
Still accelerating til it hits earth. ====================================== The height from which she dropped the ball is irrelevant. In any case, the ball was most likely moving at the greatest speed just as it hit the ground. The answer to the question is: zero.
What form of energy did the ball have before it was dropped?
The ball had potential energy before it was dropped. This potential energy was due to its position above the ground.
What is the most unknown ground hog?
A groundhog that no one's ever seen before.
Which has more kinetic energy a ball dropped from a height of 2m or a same ball dropped at 4m which has more kinetic energy just before it hits the ground?
The ball dropped from 4m height has more kinetic energy just before it hits the ground because it has a higher velocity due to falling from a greater height. Kinetic energy is directly proportional to both mass and the square of velocity, so the ball dropped from 4m height will have more kinetic energy than the one dropped from 2m height.
How many times shall a dropped ball bounce before it is in play during a soccer match?
Who has dropped the ball? The referee?! If the referee drops the ball after he interrupted the game the ball is in play when the ball touches the ground. It isn't allowed to score a goal directly from a dropped ball, two players have to touch the ball before the goal counts.
What is the point of physics?
It keeps you on the ground.

How many inches does a car have to be from the ground?
How many inches of the ground can my car be if dropped

A cricket and a football are dropped simultaneously from the top of Qutub Minar what will be the outcome?
The football will hit the ground and probably stay there. The cricket ball will be caught before it hits the ground and used enthusiastically by the grateful kiddies.
As a dropped penny falls toward the ground energy is converted to energy?
As a dropped penny falls toward the ground, potential energy is converted into kinetic energy. The higher the penny is dropped from, the more potential energy it has, which is converted into kinetic energy as it accelerates downwards due to gravity.
When do you use the word it in as sentence?
I accidently dropped it on the ground!
