A bomber jet releases its bomb from a height of 4000 meters What is the acceleration of the bomb after 5 seconds?

Perhaps you meant speed or velocity, because the vertical acceleration is constant throughout the bomb's decent, ignoring the effects of air resistance. The acceleration due to gravity is 9.8 m/s2 for all values of t.

David drops a ball from a bridge at an initial height of 70 meters what is the height of the ball to the nearest tenth of a meter exactly 2 seconds after he releases the ball?
Distance of fall in T seconds = 1/2 g T2Distance of fall in 2 seconds = (1/2) (9.8) (2)2 = (4.9 x 4) = 19.6 metersHeight of this particular ball after 2 seconds = (70 - 19.6) = 50.4 meters
How long will an object be in the air if it falls from a height of 5.9 meters?
distance (s) = 1/2 acceleration (a) x time (t) squared or s = 1/2 at^2.; a = gravity acceleration = 9.81m/s/s so time is 1.1 seconds
Can acceleration due to gravity vary with respect to height?
No, acceleration due to gravity is a constant at 9.81ms-2. It cannot be influenced by other factors such as height.
How do I work out a vertical height when it gives me kg and kJ of Ep and Gravity?
Ep (joules) = mass * acceleration due to gravity * height So: height = Ep / (mass * acceleration due to gravity)
What is the effect of increasing the height of the track on the acceleration of the object?
The effect of increasing the height of the track on the acceleration of the object is that more work is required to accelerate. It increases the gravity.
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.
How do you find the frequency if you only have seconds and height of a wave?
Assuming that seconds refers to the period, the frequency is the reciprocal (1 / period in seconds). The height of the wave is irrelevant in this case.
If a shoe is dropped from a height of 40m what is its speed after falling for two seconds?
Regardless of the height from which it is falling, (neglecting air resistance) it's speed will be 19.62 metres per second. (Acceleration from gravity is 9.81 metres per second squared, so after 1 second it is moving at 9.81 metres per second and after 2 seconds it is moving at 19.62 metres per second.
What is the effect to the result of acceleration when you lower the height of the ballistic ball?
secret
What is m g h?
mgh represents the potential energy of an object located at a height h above the ground, where m is the mass of the object, g is the acceleration due to gravity, and h is the height. It is calculated as the product of the mass, acceleration due to gravity, and the height.
WHEN A BALL IS DRoPPED FROM A height its speed increases why?
Acceleration due to the force of gravity.
A body falling freeling from a height towards the earth moves with uniform?
acceleration
