The motorcycle averages a negative 10.5 kmphacceleration. That is, the bike decelerates from 30 kmph to 9 kmph in 2 seconds. That's a change of 21 kmph over a period of 2 seconds, and that change is negative. The 21 kmph over a period of 2 seconds represents a 10.5 kmph change every second. Note that acceleration is a vector quantity. It has both magnitude anddirection. We "fudged" here and assigned a "direction" based on the direction is it traveling. It's not a biggie, but do not make the mistake of leaving off a vector when considering a velocity (which is speed plus a direction vector) or acceleration, like in this problem.
What else can I help you with?
If a car goes in 6.8 seconds how do you figure out the acceleration?
To calculate acceleration, you need to know the initial velocity of the car and its final velocity after 6.8 seconds. The acceleration can be found using the formula: acceleration = (final velocity - initial velocity) / time.
What happens to an objects speed if it travels with constant acceleration?
If an object travels with constant acceleration, its speed will change at a constant rate over time. The object's speed will increase if the acceleration is positive, decrease if it is negative, and remain constant if the acceleration is zero.
What is meant by centripetal acceleration is perpendicular to velocity?
As an object goes round in a circular path, then its velocity will along the tangent at that instant. But centripetal acceleration is normal to that tangent and so along the radius of curvature. As acceleration is perpendicular to the velocity, the direction aspect is ever changing and so the object goes round the circular path.
When an object is speeding up or slowing down or turning what is it?
The object is experiencing acceleration when it is speeding up or slowing down, and turning is an example of angular acceleration. Acceleration is the rate of change of velocity, either in speed or direction.
Does a car have negative acceleration when leaving a garage?
No, a car leaving a garage typically experiences positive acceleration as it accelerates from rest to exit the garage. Negative acceleration, also known as deceleration or braking, occurs when the car slows down or stops.
What happens when increasing the force on a object its acceleration?
goes faster
How do amusment park rides involve acceleration?
it goes fast........and when it goes faster it oicks up momentum
What is your acceleration if your car goes from 60 miles per hour to 0 in 3 seconds?
Acceleration = -20 mi/h^2
If a car goes in 6.8 seconds how do you figure out the acceleration?
To calculate acceleration, you need to know the initial velocity of the car and its final velocity after 6.8 seconds. The acceleration can be found using the formula: acceleration = (final velocity - initial velocity) / time.
Can a body moving at a constant speed have acceleration?
Yes. Acceleration is any change in velocity. Velocity is a vector quantity because it includes both speed and direction. Speed is a scalar quantity and does not include direction. Therefore, if your motion is changing direction, then you have a changing velocity regardless of your speed. And a changing velocity means you have acceleration.
When an object acceleration is negateve what happens to the object?
It goes backwards instead of forwards.
Battery light goes on during acceleration?
alternator is going out Or the belt is slipping
What happens to an objects speed if it travels with constant acceleration?
If an object travels with constant acceleration, its speed will change at a constant rate over time. The object's speed will increase if the acceleration is positive, decrease if it is negative, and remain constant if the acceleration is zero.

As acceleration is perpendicular to the velocity, the direction aspect is ever changing and so the object goes round the circular path.
In a straight line goes 3 meter per secounds to 9 meters per secound in 3 secounds what is the acceleration?
Acceleration is 2 meters / sec / sec.
What is the accelaration of a car that goes from 45 to 55 kmh?
Acceleration is the change in velocity divided by time. You need to know how long this takes to solve the problem to determine acceleration
Acceleration is distance divided by time squared?
i don't know i like cheese9/29/09 yes,for example, a car goes past you at 80mph for 10s. What is the acceleration?distance 80a= time(2) a= 10 =8 acceleration=8mph
