Force is given by Newton's second law: F = ma where F is the force, m is the mass and a is the acceleration.

80 meters. Since the only force on the car is centripetal force then:Fc = macac = v2/rFc = (mv2)/rSolve for rr = (mv2)/Fcr = (1200)(20)2/(6000)r = 80m(See my work in the link below.)
Fc = mV^2/r (2000 kg)(25 m/s)^2/(80 m) = 15625 Newtons
If body is moving in a circle with uniform or constant speed its acceleration will be uniform as velocity i.e. to say direction is changing at every point.

The centripetal force on a particle in uniform circular motion increases with an increase in the mass of the particle or the speed at which it is moving. It also increases if the radius of the circle decreases, as the force required to keep the particle in the circular path becomes greater when the circle is smaller.
=(mv*v)/r =(2000*25*25)\80 =15625N
The body which is subjected to centripetal acceleration undergoes uniform circular motion.
The only thing required for an object to show uniform circular motion is a constant centripetal force. The object will have constant speed and kinetic energy, but its velocity, acceleration, momentum, and displacement will change continuously.
-- tangential speed -- angular velocity -- kinetic energy -- magnitude of momentum -- radius of the circle -- centripetal acceleration
The velocity of an object in uniform circular motion is constant, because, velocity is the rate of change of position at a given time or speed.
No
Uniform circular motion describes motion in which an object moves with constant speed along a circular path.In physics, uniform circular motion describes the motion of a body traversing a circular path at constant speed. The distance of the body from the axis of rotation remains constant at all times. Though the body's speed is constant, its velocity is not constant: velocity, a vector quantity, depends on both the body's speed and its direction of travel. This changing velocity indicates the presence of an acceleration; this centripetal acceleration is of constant magnitude and directed at all times towards the axis of rotation. This acceleration is, in turn, produced by a centripetal force which is also constant in magnitude and directed towards the axis of rotation.
