An object with constant velocity has positive acceleration?
Answer This occurs when an object istraveling in one direction but has an acceleration in the opposite direction, which means it is decreasing in speed. For a given period of time, the speed has decreased. Acceleration is the change of velocity per second. T1 = 5 seconds V1 = 100mph T2 = 10 seconds V2= 50 mph Acceleration = (V2 - V1 ) / (T2 - T1) = (50-100)/(10-5) = -10 ft/sec/sec Positive(+) acceleration means an object will be going faster over an interval of time.
What is the acceleration of a car that moves at a steady velocity of 100 kilometers per hour for 100 seconds?
If the car doesn't change direction during that 100 seconds, then it's zero. If the car's direction changes, then the acceleration isn't zero, but the question doesn't give any information from which to evaluate it.
When the speed of an object is doubled what happens to the acceleration?
If the speed of an object is doubled while its acceleration remains constant, the object's acceleration does not change. Acceleration is a measure of how speed changes over time, so as long as the object maintains a constant acceleration, doubling its speed will not affect the acceleration.
How the terms speed velocity and acceleration are related to each other?
Speed is the rate of motion usually expressed as distance traveled per unit of time.Velocity is the rate of change of position. Both speed and direction are required. Acceleration is the rate of change in velocity. In common speech, acceleration is only for an increase in speed; a decrease in speed is deceleration. In physics, any increase or decrease in speed or change of direction is referred to as acceleration.

What is the net force on a bright red Mercedes convertible traveling along a straight road at a steady speed of 100?
Since the car is traveling at a constant speed, the net force on the car is zero. The forces acting on the car (like friction, air resistance, and engine force) are balanced to maintain the steady speed without acceleration.
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 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.

How long does it take to drive 100 miles if your going 50 miles an hour?
Two hours at a constant 50 mph, excluding speed changes or stops along the way.
How long does it take a train to get 100 miles going 35 mph?
It would take a train going 35 miles per hour approximately 2 hours and 51 minutes to travel 100 miles assuming the constant speed of 35 miles was kept.
What is the speed in meters per second if you are running 100 meters in 12 seconds at a constant speed?
s=d/ts= 100 / 12s= 8.33ms-1
What will the acceleration and top speed of the new Alfaromeo Mito GTA be?
Acceleration: 5 seconds from 0 to 100 km/h (0 to 60 mph) Top speed: 250 km/h (155 mph)
What does a horizontal line on a velocity time graph show for acceleration?
Any curved line will indicate a change in acceleration. Straight lines with slope indicate a steady velocity and straight lines with zero slope indicate a lack of motion.If the X axis (left to right) is for time and the Y axis (up and down) is for speed, it would curve up.
