What else can I help you with?
If you drop an object it will accelerate downward at a rate of 9.8 meters per second squared if you instead throw it downwards its acceleration will be greater or less 9.8 meters per second?
Whether the object is dropped, thrown downwards, thrown upwards, or thrown horizontally, its downward acceleration is the same 9.8 meters per second2. If it's thrown downwards, however, its speed at any instant is greater than the speed at the same instant would be if it had only been dropped, since it has some speed before the acceleration begins.
Can the velocity of an object at an instant of time be greater in magnitude than the average velocity over a time interval containing the instant. Can it be less?
Yes, the velocity of an object at an instant of time can be greater than the average velocity over a time interval containing the instant, especially if the object is changing velocity rapidly. Similarly, it can also be less than the average velocity, especially if the object is reversing direction or slowing down during that time interval.
When a body is projected simultaneously from the top of the building with different initial horizontal velocity which of the two will hit the ground first?
Ignoring air resistance, the horizontal component of velocity has no connection with, and no effect on, the vertical component. Two bodies that leave the top of the building simultaneously with the same vertical velocity hit the ground at the same time, regardless of their horizontal velocities or their masses. That's the same as saying that a bullet fired horizontally from a gun and a bullet or a stone dropped from the gun's muzzle at the same instant hit the ground at the same instant. Strange but true.
A rock is dropped at the same instant that a ball at the same elevation?
Any object that falls on Earth, no matter its size, will fall at the same speed. Drop a rock and a ball and both will accelerate at the same rate. The only thing that would slow them down is air resistance.
When dropped from a building a cricket ball and a football have the same velocity or they hit the ground at same instant which more correct answer?
Both the cricket ball and football will hit the ground at the same time, regardless of their velocities. This is because they are both subject to the same acceleration due to gravity, causing them to fall at the same rate.
If a cannon fires a cannonball horizontally and you drop a cannonball at the same time which will hit the ground first?
A cannonball fired horizontally and one dropped from the height of the muzzle simultaneous with the shot will hit the ground at the same instant, provided only that the ground under the muzzle and the ground where the shot lands are at the same elevation, i.e. the shot was not fired off the edge of a cliff or into the side of a mountain. To solve this kind of problems, it often helps to separate the movement, or the speed, into vertical and horizontal components. In this case, the vertical component of the speed is the same.
If you drop an object it will accelerate downward at a rate of 9.8 meters per second squared if you instead throw it downwards its acceleration will be greater or less 9.8 meters per second?

If it's thrown downwards, however, its speed at any instant is greater than the speed at the same instant would be if it had only been dropped, since it has some speed before the acceleration begins.
What would happen if an apple and an orange were dropped from the same height at the same time?
They would both SPLAT on the ground at the same instant.
If you dropped a brick a tennis ball and a feather from a building on the Moon in what order would they land?
They would land in the same order in which I dropped them. If I dropped them all at the same instant,then they would all land at the same instant. The same can be said for a truck, a cinder block, and a hair.
Can the velocity of an object at an instant of time be greater in magnitude than the average velocity over a time interval containing the instant. Can it be less?
Yes, the velocity of an object at an instant of time can be greater than the average velocity over a time interval containing the instant, especially if the object is changing velocity rapidly. Similarly, it can also be less than the average velocity, especially if the object is reversing direction or slowing down during that time interval.
A ball is dropped from the roof of a building The mass of the ball is 3.0 kg What is the potential energy of the ball in the instant that it is exactly 18.0 meters above the ground?

When was atomic bomb drop on hiroshima?

A rock is dropped at the same instant that a ball at the same elevation?
Any object that falls on Earth, no matter its size, will fall at the same speed. Drop a rock and a ball and both will accelerate at the same rate. The only thing that would slow them down is air resistance.
