What is the acceleration of a car that maintains a constant velocity of 100km per h for 10 seconds?
Acceleration is the time rate of change of velocity. If velocity is constant, then acceleration is zero. Note: "100 km per h for 10 seconds" is a constant speed, but not necessarily a constant velocity, since we're told nothing about the direction. If the car moves in a perfectly straight line during those 10 seconds, then its velocity is constant. If it makes a curve, then its velocity is not constant even though its speed is, and there is acceleration.
What is the average velocity of a car that accelerates from 15 meters per second to 25 meters per second in 10 seconds?
If the acceleration was constant (15 + 25) /2 = 20 (time does not figure into the averaging at all!)
What is the acceleration of a car that maintains a constant velocity of 100 kilometers per hour for 10 seconds?
The answer is very simple. The words "constant velocity" are the definition of zero acceleration.
You throw a ball straight up with a velocity of 40 meters per second What is the ball's velocity after 5 seconds?
it is 10 meters per second straight down
How does constant velocity differ from constant acceleration?
Constant velocity is a measure of distance traveled per unit of time at a uniform speed, such as miles per hour or feet per second. Constant acceleration is a measure of a continuing increase in velocity per unit of time, as when a car speeds up from 30 miles per hour to 40 miles per hour in 5 seconds, then from 40 miles per hour to 50 miles per hour during the next 5 seconds. It will then have had a constant acceleration of 10 miles per hour per 5 seconds.
Does motion of seconds hand of a watch represent uniform velocity?
No, the motion of the seconds hand of a watch is not an example of uniform velocity. The seconds hand moves in a circular motion at a constant speed, rather than moving in a straight line at a constant velocity. Uniform velocity refers to motion in a straight line with a constant speed.

A student riding her bicycle on a straight flat road covers one block every 7 seconds if each block is 100m long she is traveling at?
Constant speed and constant velocity

You throw a ball straight up with a velocity of 40 meters per second. What is the ball's velocity after 3 seconds?
You throw a ball straight up with a velocity of 40 meters per second. What is the ball's velocity after 3 seconds?
A skydiver steps from a helicopter and falls for 5 seconds before reaching her terminal velocity During this 5 second interval her acceleration will?
increase- your speed will increase until terminal velocity is reached. From there it will stay constant.
What is the velocity of a ball thrown 20 ft in 4 seconds?
In the case of constant velocity (or speed), velocity = distance / time.

The answer is very simple. The words "constant velocity" are the definition of zero acceleration.
A car accelerates from a standstill to 60 kmhr in 10 seconds What is its acceleration?
The acceleration of the car can be calculated using the formula: acceleration = (final velocity - initial velocity) / time. Converting the initial velocity of 0 km/hr to m/s and final velocity of 60 km/hr to m/s, and plugging in the values, we get the acceleration to be 2 m/s^2.
You throw a ball straight up with a velocity of 40 meters per second. What is the ball's velocity after 5 seconds?
The velocity of the ball will be -30 m/s (downward) after 5 seconds due to gravity.
You throw a ball straight up with a velocity of 40 meters per second What is the ball's velocity after 5 seconds?
it is 10 meters per second straight down
