A car is travelling at a given instant 40m per ecs on a circular road of radius 400m.its speed is increasing at the rate of 3m per sec.what is its tangential acceleration?

if the speed is increasing at 3 m/s2 then that is the acceleration (if i understand the question correctly)

What is the acceleration that occurs when an object moves at a constant speed in circular motion called?
It's called 'centripetal acceleration', whether or not the speed is constant or the path circular.
For a car moving around a circular track at a constant speed the acceleration is?
constant speed=0 acceleration Acceleration is the change in speed. If the speed doesn't change(ie constant) the acceleration is zero.
Examples of constant speed but changing acceleration?
A body moving with constant speed in a circular path has acceleration changing at every point.
A race car is travelling at constant speed around a circular track What happens to the centripetal acceleration of the car if the speed is doubled?
It increases by a factor of 4, because Fc = (mv2)/r. Fc = ma. so we conclude that the relationship between a and v is a squared relationship.
A car moves in uniform circular motion around a curve in the road What is the direction of the car's acceleration?
If the speed is constant, the acceleration is toward the center of the circle.
Why tangential acceleration is not produced in uniform circular motion?
Because there is no tangential force acting on the object in uniform circular motion. The proof that there is no tangential component of acceleration is the fact that the tangential component of velocity is constant.
What is an example of tangential and centripetal acceleration?
If an object follows a circular path, it must have a centripetal force on it to keep it moving in a circle. Centripetal means "toward the center of the circle". The force causes Centripetal acceleration toward the center witch is along the radius of the circular path. Tangential acceleration occurs at a Tangent to the circular path and is always perpendicular to the centripetal acceleration. Always perpendicular to the radius of the circle.
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.
What is the difference between tangential and radial acceleration?
Answer Both refer to an object that is in a cirular motion. Radial Acceleration is a velocity change of the object as it moves away from the center of rotation. Tangential Velocity is a change of velocity of the object as it moves in a line that is tangential to the circular path it is moving.
Objects that move along a circular path are they accelerated toward the outer edge of the circle?
Actually, objects moving around a circular path have two accelerations i.e. radial acceleration and tangential acceleration. Radial acceleration is towards the radius whereas tangential acceleration is the acceleration along the direction of the tangent to the path of the motion. So, I would say yes, they are accelerated towards the outer edge of the circle.
Quantity that remains constant during uniform circular motion?
-- tangential speed -- angular velocity -- kinetic energy -- magnitude of momentum -- radius of the circle -- centripetal acceleration
Can a body moving with constant speed has acceleration?
Yes. Eg : in case of a uniform circular motion. In general, for every motion in which direction of motion of particle keeps changing continuously and the particle moves with same speed, then the net acceleration is non-zero, although tangential acceleration is zero.
What term describes a change in the speed of an object in circular motion?
VelocityMore Information:Its velocity, or its rate of change of position.Velocity is stated as distance per time (kilometers per hour, meters per second, etc.).
What is centripital acceleration?
acceleration in a circular motion :)
Is acceleration uniform in uniformly circular motion?
yes, acceleration is constant in uniform circular motion
What is an example of Circular acceleration?
a satellite in orbit; it is moving at constant speed but is accelerating outward in circular acceleration, balanced by gravity acceleration (centripetal force).
Why A stone tied at the end of a string is whirled in a circle If the string breaks the stone flies away in tangential direction?
As force acting in a circular path is always tangential to the path
