We'll make the assumption that the boy being pushed is wearing skates that allow frictionless translation.
Step 1:
Calculate the acceleration (a) that would result by a 25kg mass being acted upon by a 500N force (f).
f = ma
a = f/m = 500N/25kg = 20m/sec2
Step 2:
Calculate the contact time (t).
We know the initial velocity (V0) is zero.
We know the final velocity (Vf) is 20m/sec.
From Step 1, we have determined the acceleration (a) to be 20m/sec2
Vf = V0 + at
at = Vf - V0
t = (Vf - V0)/a = (20m/sec - 0m/sec)/(20m/sec2) = 1 sec

What is the term for the force exerted by an object when it is pushed by another object?
The term for the force exerted by an object when it is pushed by another object is "contact force" or "applied force." This force occurs when one object comes into direct contact with another object and pushes or pulls it.
What is the frictional force that the truck exerts on the box in the previous situation?
The frictional force that the truck exerts on the box in the previous situation is the force that opposes the motion of the box as it is being pushed or pulled by the truck.
If a ball is rolling in a straight line and you push it to the right it's velocity Will?
If you push a ball rolling in a straight line to the right, its velocity will change in the direction you pushed it, affecting its speed and direction of motion. The velocity will have a component in the direction you pushed it, as well as any remaining component from its original motion.
What are two pairs of action-reaction forces involving a bucket?
When a person lifts a bucket upward, the person exerts an upward force on the bucket, and the bucket exerts a downward force on the person. When a bucket is pushed along the ground, the person exerts a forward force on the bucket, and the bucket exerts an equal and opposite backward force on the person.
How does a balloon-powered race car apply to newtons laws of motion?
A balloon powered car is moves because the balloon pushes out air. Whenever something exerts a force on something else (in other words, the balloon is exerting force on the air), then the object being pushed always exerts an equal and opposite reaction force on the object exerting force on it (in other words, the air exerts force on the balloon). Because the balloon is attached to the car, when the balloon is pushed by the air, the car is pushed. The law that for every force there is an equal and opposite reaction force is Newton's Third Law of Motion.
What is another word for being physically pushed?
Shoved or pushed are alternative words for being physically pushed.
A science book is being pushed across a table Can the book have a constant speed and a changing velocity?
It can have a constant speed, and a changing velocity, but it cannot have the two at the same time. Remember: Velocity = speed with a directional component.

When the gas pedal is pushed what force causes the change in velocity?
When the gas pedal is pushed, the engine generates power which is transferred to the wheels, causing them to rotate. The force of friction between the tires and the road surface allows the vehicle to accelerate and change velocity.
How can you use the words cause and effect to explain the 3rd newton law?
Newton's third law states that for every action, there is an equal and opposite reaction. This means that whenever one object exerts a force on another object, the second object exerts an equal force in the opposite direction. The cause is the action force, and the effect is the reaction force that occurs as a response to the initial force.
