Using the formula F = ma, where F is the force, m is the mass, and a is the acceleration, we solve for the mass of the ball. Given F = 20 N and a = 4.0 m/s^2, we have 20 = m * 4.0. Therefore, m = 5 kg.

What is the accereleration of 2kg mass slding down a frictionless ramp?

The acceleration of a 2kg mass sliding down a frictionless ramp is equal to the acceleration due to gravity, which is approximately 9.8 m/s^2. This acceleration remains constant as there is no force acting against the motion of the mass on a frictionless surface.


Can a frictionless surface exert normal force?

No, a frictionless surface cannot exert a normal force because the normal force is a force exerted perpendicular to the contact surface and is necessary to counteract the force of gravity or any other downward force. Without friction, there is no need for a normal force to counteract any horizontal force component.


What happens when three blocks are placed on a horizontal frictionless surface?

When three blocks are placed on a horizontal frictionless surface, they will remain stationary and not move because there is no force acting on them to cause them to move.


What happens when three blocks are placed on a frictionless horizontal surface?

When three blocks are placed on a frictionless horizontal surface, they will remain stationary unless an external force is applied to them. If a force is applied to one of the blocks, it will move in the direction of the force, while the other blocks will remain stationary due to the absence of friction.


The work required to accelerate an object on a frictionless surface from a speed v to a speed 2v is?

The work required to accelerate an object from speed v to 2v on a frictionless surface is equal to the change in kinetic energy, which can be calculated as 3/2 times the initial kinetic energy. This increase in kinetic energy corresponds to the work done by the force causing the acceleration.

Will a skateboard go faster if you push it with the same force for a longer time?

Yes. The force is measured as "acceleration" and is meters per second per second (or velocity per second) or the first derivative of velocity. On a frictionless surface in an environment without air resistance, and if the skateboard is a frictionless mechanism, if the skateboard is moving at a constant velocity, that means the acceleration is zero, which means that there is no force being applied to it and it is a body in motion staying in motion.


When a horizontal force equal to its weight is applied to an object on a frictionless surface what is its acceleration?

9.8 meters (32.2 feet) per second2 horizontally, provided the exercise is performed on or near the Earth.

What will happen if you apply a force on top of a disk kept on a frictionless surface?

The disc will slow down as a result of the friction applied by the force.

What is the work done against the gravity when a body is moved horizontally along a frictionless surface?

No work is done against gravity when a body is moved horizontally along a frictionless surface because the force of gravity acts perpendicular to the direction of motion. Work is only done when a force is exerted in the direction of motion.


What is the net force acting if an object is moving along a surface with a constant acceleration?

If the object is moving along a horizontal surface with a constant acceleration,then the net vertical force on it is zero, and the net horizontal force on it is(the pushing force) minus (any kinetic friction force where it rubs the surface).The numerical value of that net force is(the acceleration) times (the object's mass).


How do you have zero net force but still have motion?

An object can have zero net force but still be in motion if it is moving at a constant velocity. In this case, the forces acting on the object are balanced, resulting in no acceleration. For example, an object traveling at a constant speed on a frictionless surface would have zero net force acting on it.


What is critical acceleration?

Critical acceleration is the minimum acceleration required to cause an object to start moving or sliding on a surface. It is the point at which the frictional force between the object and the surface is overcome by the applied force.
