the force acting down the slope = sin 30 * 25 (kg) = 0.5 * 25 = 12.5 kg = (12.5 * 9.806 ) 122.575 newtons = resultant force of (122.575-120 ) 2.575 newtons downhill giving downhill acceleration of (using f=ma) 0.103 (m/s)/s
yes
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.
9.8 meters (32.2 feet) per second2 horizontally, provided the exercise is performed on or near the Earth.
The mass of the box is 16 kg (48.0N / 3.00 m/s^2).
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.
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.
A wall is an example of a surface standing at 90 degrees from the horizontal.
Perpendicular
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.
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).
Acceleration values can vary widely depending on the situation. In scenarios with constant acceleration, such as free fall or motion on a frictionless surface, the values will be relatively constant. However, in real-world scenarios with changing forces or friction, acceleration values can vary significantly.
In physics, a hook pan refers to a frictionless horizontal surface attached to a spring scale used for measuring force. This setup allows for the measurement of force applied parallel to the surface with minimal interference from friction.
