Calculating Acceleration of a Block on an Inclined Plane

How can we calculate the acceleration of a block sliding down a frictionless inclined plane?

What is the formula to find the acceleration of the block?

Answer:

To calculate the acceleration of a block sliding down a frictionless inclined plane, we can use the formula:

Acceleration (a) = (Final Velocity - Initial Velocity) / Time

When dealing with a block sliding down an inclined plane, we need to consider the forces acting on the block. The force that pushes the mass down the incline can be calculated using the formula mg x sin A, where m is the mass of the block, g is the acceleration due to gravity, and A is the angle of the plane.

Additionally, we can use the formula m x a to calculate the force, where m is the mass of the block and a is the acceleration. The original acceleration in the plane can be determined by finding the difference between the two initial velocities and dividing by the given time:

Acceleration (a) = (6.13 m/s - 1.54 m/s) / 1.70 s = 2.70 m/s^2

By knowing the acceleration, we can find the angle of the plane by using the formula sin A = a / g, where g is the acceleration due to gravity. In this case, the angle of the plane is calculated as:

Angle A = arcsin(0.275) = 15 degrees

This process allows us to determine the acceleration of a block sliding down a frictionless inclined plane and find the angle of the plane based on the given data.
