What is the velocity of a 4.5 Pound object falling thirty feet?
Ignoring air resistance ... Any object dropped near the Earth's surface reaches a speed of 43.9 feet per second after falling 30 feet. The velocity is 43.9 feet per second down. The object's weight makes no difference.
An object is moving at a constant velocity of 10 ms how far what distance will it travel in 30 seconds?
For such problems, you can use the formula:distance = speed x time
How is the velocity of an object different from the speed of an object?
Velocity of a moving body is its rate of DISPLACEMENT with respect to time. But speed is distance traveled per unit time. The difference between speed and velocity is that velocity has a direction. 30mph is a speed. 30mph due north is a velocity. Well not really because 'north' is arbitrary but you get the idea. Displacement is both a distance and direction. 30 miles is a distance. 30 miles to the north is a displacement. A two part quantity like velocity or displacement is called a 'vector quantity'. A one part quantity (speed, distance etc) is called a 'scalar quantity'.
How do you calculate the speed of something dropped from 30 feet in the air?
The speed of an object dropped from a certain height can be calculated using the equation v = √(2gh), where v is the speed, g is the acceleration due to gravity (approximately 9.8 m/s^2), and h is the height. In order to calculate the speed in feet per second, you would need to convert the height of 30 feet to meters (i.e., 30 * 0.3048).
Can speed equal velocity?
Speed is the size of velocity. But velocity also has a direction. "30 miles per hour" is speed. "30 miles per hour north" is velocity.

What is the kinetic energy of an object that has mass if 30 kilograms moves with a velocity of 20 mm?
To get the kinetic energy of an object you need both mass and velocity. As it stands it can't be answered, as "mm" isn't a recognized unit of velocity
What is an objects velocity?
An object's velocity is it's speed plus direction. example: 55mph south Hope this helps:)
An object is moving at a constant velocity of 10meters per second how far will it travel in 30 seconds?
10 x 30 = 300 metres.
What is the kinetic energy of an object that has a mass of 30 kiloand moves with a velocity of 20ms?
6,000 joules at 20m/s
An object is moving at a constant velocity of 10 ms how far what distance will it travel in 30 seconds?
For such problems, you can use the formula:distance = speed x time
What is the velocity of an object that starts at 45 mph and accelerates at a rate of -10 mphsec for 3 seconds?
the final velocity = initial velocity + acceleration x time; since acceleration is negative final velocity = 45 - 10x3 = 45 -30 = 15 mph
An object is released into the air at an initial height of 6 feet and an initial velocity of 30 feet per second The object is caught at a height of 7 feet How long is the object in motion?
23 sec
The speed and direction of a moving object is called?
velocityYou mean, Velocity.. Velocity is the rate of change of displacement (position). It is a vector physical quantity; both magnitude and direction are required to define it. The scalar absolute value (magnitude) of velocity is speed, a quantity that is measured in meters per second (m/s or ms−1) when using the SI (metric) system.I linked my source.Speed in a specific direction is called velocity.speed is a scalar unit whereas velocity is a vector unit.Speed is the rate of change of position. In vector terms, speed is the magnitude of the velocity. (Velocity is speed and direction; speed is the velocity along a given direction.)

If there is a constant velocity of 30 ms. What is its acceleration?
Unless the object is changing its direction, it is not accelerating. Constant velocity implies that speed and direction are constant, and for acceleration to occur, either speed, direction, or both values must be changing.
