What else can I help you with?
How would you describe your motion in terms of velocity and acceleration as you ride in a car down the street come to a red light wait for the green light and then start off again?
As the car moves down the street, the velocity is positive. As it comes to a red light and stops, the velocity decreases to zero. Waiting at the red light, the acceleration is zero. When the light turns green and the car accelerates, the velocity increases from zero to a positive value, and the acceleration is positive.
What is the acceleration of a car going a constant speed of 100?
If the car is going at a constant speed of 100 km/h, then its acceleration is zero. Acceleration measures the rate of change of velocity, and since the car's speed is not increasing or decreasing, there is no acceleration.
What is the acceleration of a car moving along a straight line path that increases its speed from zero?
The acceleration of the car is equal to the rate of change of its speed over time. When a car goes from zero speed to a higher speed, it experiences positive acceleration in the direction of its motion.
What is acceleration of a Car that is going at a steady speed of 50 mph?
The acceleration of a car at a steady speed of 50 mph is zero. Acceleration is the change in velocity over time, so when the car is maintaining a constant speed, there is no change in velocity and therefore no acceleration.
What is acceleration of a car that is going at a steady speed of 60 mph?
The acceleration of a car traveling at a steady speed of 60 mph is zero. Acceleration refers to a change in velocity over time, so a steady speed means there is no change in velocity and therefore no acceleration.
What is the acceleration of a car when the forces are balanced?
Zero.

Can a car move around a circular racetrack so that the car has a tangential acceleration but no centripetal acceleration?
No, If a car moves around a circular race track with any constant speed, the acceleration is directed towards the centre. So it has a centripetal acceleration. The tangential acceleration would be irrelevant unless the car has an instantaneous tangential velocity of zero. Then the centripetal acceleration is zero. However, this would only exist for that small instant in time.
Can object have zero acceleration and nonzero velocity at the same time.give example?
Yes, an object moving at a constant velocity has zero acceleration even though it has a non-zero velocity. For example, a car driving at a steady speed on a straight highway has a constant velocity but zero acceleration.
What are examples for zero acceleration?
Anything that doesn't move; anything that moves at a constant velocity (for example, a car on a straight road, at a constant speed of 70 km/hour).
When a car rounds a curve it's acceleration is zero?
Actually, a car always accelerates on a curve. This is because acceleration, like the velocity it alters, is a vector that has both magnitude and direction. Since taking a curve involves a change of direction, there must be an acceleration to alter the direction; otherwise, the car can only continue straight.
When a cars velocity is uniform what it is acceleration?
When a car's velocity is uniform, its acceleration is zero. This means that the car is not speeding up or slowing down, but maintaining a constant speed. Uniform velocity indicates that there is no net force acting on the car to change its motion.
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.
