What is the speed of the block at the bottom of the incline?
The velocity of the block at the bottom of the incline is therefore 9.90 m/s.
What is the work done by friction as the block slides on the flat horizontal surface?
Therefore, the work done by friction as the block slides on the flat horizontal surface is −58.8525J.
What is the work done on the block by friction?
The work done by friction is the force of friction times the distance traveled times the cosine of the angle between the friction force and displacement; hence, this gives us a way of finding the distance traveled after the person stops pushing.
What is the work done by gravity as the block slides down the incline?
The work done by gravity as the block slides down the inclined plane is equal to the negative change in potential energy.
Why do objects slide down a slope?
The parallel component of the force of gravity is not balanced by any other force. This object will subsequently accelerate down the inclined plane due to the presence of an unbalanced force. It is the parallel component of the force of gravity that causes this acceleration.
What happens when a block slides down a frictionless incline?
Now up your study game with Learn mode. As a block slides down a frictionless incline, which of the following statements is true? Its speed increases and its acceleration remains constant. A crate remains stationary after it has been placed on a ramp inclined at an angle with the horizontal.
How do you find the mass of a frictionless incline?
Mass on Frictionless Incline Application of Newton’s second lawto mass on incline. For a frictionless incline of angle degrees, the acceleration is given by the acceleration of gravity times the sine of the angle. Acceleration =m/s2 compared to 9.8 m/s² for freefall.
What is the speed at the bottom of the incline?
If the height of the incline is h=m, then the time to slide down the incline from rest would be t=seconds, compared to a time of t=seconds to drop from that height. The speed at the bottom of the incline would be m/s. These calculations can be done with the motion equations.
What is the application of Newton’s second law to mass on incline?
Application of Newton’s second lawto mass on incline. For a frictionless incline of angle degrees, the acceleration is given by the acceleration of gravity times the sine of the angle. Acceleration =m/s2 compared to 9.8 m/s² for freefall.
