When a ball is hit with a given force why does contact over a long time impart more speed to the ball?

The longer the time the bigger the momentum Fdt= mv. For the mass m the increase in momentum (dt) gives more v, the velocity and speed.

What is the measure of intertia in an object?
Inertia is the tendency of an object to remain still, or remain moving at a constant speed in a straight line, unless acted upon by an outside force. Thus the measure of this quality is the mass of an object since acceleration is equal to the force applied to an object multiplied by its mass. The greater the mass, the less acceleration a given force will impart to it. In order to impart greater acceleration to a given mass, greater force is needed.
What is a non contact force that makes something speed up?
Gravity.
Friction is a force that speed's up motion between two surfaces that are in contact?
no. it is the opposite. friction is the force that slows down things in motion in contact with each other.
What are two factors that can affect speed?
Thrust and friction in the environment. Ignoring friction, the two chief factors are the force of acceleration and mass, which determines how much force is required to achieve a given speed (more technically the change of velocity: speed in a given direction).
How does force affect speed of an object?
The relationship is given by Newton's Second Law. Briefly, a net force (an unbalanced force) will accelerate the object, that is, it will change its velocity.

How do you compute the force of a given mass at a constant speed?
The force on a mass moving at a constant speed and direction is 0.
Is the force the speed?
Force is not speed. Force is what makes an object change its speed. In other words force produces acceleration, which changes speed. The exact relation is given by one of Newton's laws of motion f=ma you can rewrite this as acceleration= force / mass

Gravity.
How can you find force when given distance and speed?
You cannot. Force is mass times acceleration. You have neither.

How do you find force when given a constant speed and force of friction?
If the speed is constant, then the group of forces acting on the object is balanced. So the portion of the force acting in the direction of the motion must be equal and opposite to the force of friction.
How does force affect speed of an object?
The relationship is given by Newton's Second Law. Briefly, a net force (an unbalanced force) will accelerate the object, that is, it will change its velocity.
How do you find mass if you are given velocity force and speed?
force=mass x acceleration. you have force lets say 100N. you are given a velocity of lets say 10m/s at the first second. and you are given speed. if you are given one speed, then you are given the change in velocity (your acceleration). if you are given multiple speeds, then you can figure out your change in velocity of the amount of time the speeds are given as (also your acceleration). So lets say you are given a speed of 30m/s at the third second (second second sounds redundant). Assuming acceleration is constant as always, 30-10=20m/s over 2 seconds. So 20/2=10m/s2. now you have force and acceleration. 100= m x 10m/s2. m=10kg.
