The total value of the frictional forces acting on the bike and its rider would be 400 N, which is equal in magnitude to the pedal force applied. This is necessary to balance the pedal force and maintain a constant speed when the bicycle is moving at a constant velocity.

Condition where tangential force is considered almost horizontal?
In the context of physics, when the tangential force acting on an object is almost horizontal, it means that the force is predominantly acting parallel to the surface of the object. This scenario often occurs when an object is moving along a horizontal surface and experiences frictional forces that oppose its motion. The horizontal component of the force is crucial for determining the object's acceleration and frictional interactions.
Why does a projectile maintain its horizontal component of velocity?
A projectile maintains its horizontal component of velocity because there are no horizontal forces acting on it once it's in the air. In the absence of air resistance and other external forces, the projectile continues to move horizontally at a constant velocity as per Newton's first law of motion.
Which describes a bicycle going at a constant speed in a constant direction?
A bicycle moving at a constant speed in a constant direction has no changes in its velocity or acceleration. It is a balanced state of motion where the bike maintains its speed and direction without any external forces acting on it.
Object with weight W is dragged along a horizontal plane by a force acting along a rope attached to object?
The object will experience a frictional force equal in magnitude but opposite in direction to the applied force. The net force acting on the object will be the difference between the applied force and the frictional force. This net force will cause the object to accelerate or move at a constant speed depending on the balance of forces.
Why horizontal motion is constant?
Horizontal motion is constant when there are no external forces acting on an object in that direction. According to Newton's first law of motion, an object in motion will stay in motion at a constant velocity unless acted upon by an external force. This is why horizontal motion can remain constant when there is no acceleration or deceleration.
What is the resulting motion of forces acting on a unbalanced bicycle?
Constant acceleration is the resulting motion of forces acting on an unbalanced bicycle.

A bicycle is moving with constant velocity to the east. What is true of the applied forces?
The applied forces on the bicycle would be balanced. The force applied by the rider in pedaling is equal and opposite to the forces of friction and air resistance acting on the bicycle. This results in a net force of zero, allowing the bicycle to move with constant velocity.
If a cart is observed moving at a constant velocity along a horizontal frictionless track is there a constant net force acting on it in the direction of motion?
No force is acting on it. Constant velocity means no acceleration, which means no force, from f=ma, no 'a' no force.
Why can you hold an eraser against the board and prevent it from slipping down vertically by applying a horizontal force?
When you apply a horizontal force on the eraser, it creates a frictional force between the eraser and the board in the opposite horizontal direction. This frictional force counteracts the force of gravity acting on the eraser, preventing it from slipping down vertically. This is known as static friction, where the surfaces are not sliding past each other.
Why does the horizontal component of the speed not change values?
The horizontal component of velocity remains constant for an object in projectile motion because there are no horizontal forces acting on the object once it is in motion. In the absence of air resistance and other external forces, the object will continue to move horizontally at a constant speed.
Why does the horizontal component of velocity for a projectile remain constant while the vertical component changes?
The horizontal component of velocity remains constant because there are no horizontal forces acting on the projectile (in the absence of air resistance). The vertical component changes due to the force of gravity, which accelerates the projectile downwards.
Why does the vertical component of velocity for a projectile change with time where as the horizontal component of velocity doesn't?
The vertical component of velocity changes due to the influence of gravity, which accelerates the projectile downwards as it moves. The horizontal component of velocity remains constant because there is no horizontal force acting on the projectile, assuming air resistance is negligible.
