Assuming the the object was dropped and is relatively close to the earth's surface; then we can say that since:
distance=(1/2)(acceleration)(time)2 ; 10m=(1/2)(9.8)(time)2 ; then the time spent falling is apprx. 1.429s, multiplied by the acceleration (9.8 m/s2) gives us a velocity of apprx. 14.00 m/s

What is a momentum of a object of 1kg and a velocity of 10 ms?
momentum=mass*velocity 1*10=10Ns
What do you need to know to determine momentum?
To find the momentum of an object you must know the mass of the object and the velocity at which it travels. Example: A 50kg man runs at 10m/s. What is his momentum? Momentum = Mass x Velocity 50 x 10 = 500 kgm/s
What does it mean for an object to accelerate at 10 mss use an examble?
Acceleration is the rate at the speed or velocity of a body increases per unit time. An object that accelerate at 10 mss means the rate at which it's velocity is changing per unit second is 10m/s. For instance, an object accelerating at 10 mss for 3 second will have a velocity of 30m/s.
How do I find the average acceleration of a moving object in a positive x direction that went from a velocity of 89 m/s to a velocity of 19 m/s in 7.0 seconds?
19 - 89 = -70 -70/7 = -10 It accelerated at -10 m/s^2
What will happen to the velocity of an object that increases its mass from 5 kg to 10 kg and maintains a momentum of 10 kgm slash s?
It will decrease.
What is a momentum of a object of 1kg and a velocity of 10 ms?
momentum=mass*velocity 1*10=10Ns
What describes how fast an object is moving and in what dirrection?
The maximum speed of any object is hardly equal to speed of light which is 3*10^8 approximately.
A 10 N force acts on a 2kg object for 3 seconds If the object was initally at rest the KE of the object after 3 seconds is?
Use the formula force = mass x acceleration, to find out the acceleration. Next, velocity = acceleration x time, to find the velocity. Finally, use the formula KE = (1/2) x mass x speed2, to find the kinetic energy.

What is acceleration and velocity?
Acceleration and velocityVelocity - which is not quite the same thing as speed -- is the measure of the rate of change in position. In other words, to calculate velocity, we divide the change in an object's displacement -- how far it moved -- by the time it took to move. If an object moves, say, 100 feet in 10 seconds, its velocity is 100/10 = 10 feet per second (ft/s). Acceleration is the rate of change of velocity. If an object increases its speed from, say, 10 ft/s to 60 ft/s in five seconds, its acceleration is 10 feet per second per second, or 10 feet per second squared (ft/s2).How did we arrive at that figure? Divide the change in velocity by the change in time. The change in velocity is 60 - 10 = 50 ft/s. The change in time is 5 - 0 = 5 s. Hence, 50/5 = 10 ft/s2.
What is the momentum of an object that is moving in a straight line at a speed of 10 ms and has a mass of 10 kilograms?
Simply multiply the velocity times the mass.
What will happen to the velocity of an object that increases its mass from 5 kg to 10 kg and maintains a momentum of 10 kgm slash s?
It will decrease.
How fast an object move?
The maximum speed of any object is hardly equal to speed of light which is 3*10^8 approximately.
What is the average velocity of a free falling object during a 10 s interval?
Acceleration of gravity = 32.2 ft/sec2If the object started from rest, i.e. nobody threw it down, thenInitial velocity = 0Final velocity = (10 x 32.2) = 322 ft per sec.Average = 1/2 ( Vi + Vf ) = 161 ft per sec.
Is it possible for an object to move for 10 seconds at a high speed and end up with an average velocity of zero?
Yes
