Momentum = mass x speed so speed = momentum/mass or V=P/m
The speed at the end of the time is (speed at the beginning of the time) plus (acceleration x length of time)
You don't have enough information to find the speed. Unless perhaps you explain the specific situation with a bit more detail.
You didn't specify what data is given. In general, for constant speed, the following formula is important (just use the definition of speed): speed = distance / time; or distance = speed x time. If distance is in km and time in hours, speed will be in km/hour; if distance is in meters and time in seconds, speed will be in meters/second.
If the displacement of the object (its position) can be described as a functional or algebric equation, you can find the instant speed of this object by calculating the derivative of its displacement equation, knowing that speed is the first derivative of position and acceleration, its second.
Reteradation will be half of acceleration
Calculate the gradient of the curve which will give the acceleration. Change the sign of the answer to convert acceleration into retardation.
acceleration times speed
The answer depends on what information you are given.

ten feet for every ten miles an hour
Divide the distance by the time; the quotient is speed.
Momentum = mass x speed so speed = momentum/mass or V=P/m
The speed at the end of the time is (speed at the beginning of the time) plus (acceleration x length of time)
Distance = time * average speed (velocity) Average speed = Distance/time
Retardation is the opposite of acceleration.It starts from a non zero uniform velocity.For this to happen any velocity (not zero) of a vehicle should go on decreasing.The rate of decreasing may be anything.If it is decreasing then that is retardation.
