A 6.0 kg block of ice rests on a surface that is tilted by = 12°. Find the acceleration of the block ignoring any friction.

Why did the block of ice go to school? It wanted to become an ice cube-ist! But in all seriousness, to find the acceleration of the block, we can use trigonometry. The gravitational force acting on the block can be broken down into two components: one perpendicular to the tilted surface, and one parallel to the tilted surface. The component perpendicular to the surface will balance out the normal force, leaving only the component parallel to the surface to cause acceleration. We can find this component by multiplying the gravitational force (m * g) by the sine of the angle of tilt (12°). So, the acceleration (a) of the block can be calculated using the equation a = (m * g * sinθ) / m, where m is the mass of the block, g is the acceleration due to gravity, and θ is the angle of tilt. Plugging in the values, we get a = (6.0 kg * 9.8 m/s^2 * sin(12°)) / 6.0 kg. Simplifying that, we find a ≈ 1.47 m/s^2. So, the acceleration of the block is approximately 1.47 m/s^2.

To find the acceleration of the block, we can use Newton's second law of motion, which states that the net force acting on an object is equal to the mass of the object multiplied by its acceleration.

In this case, the only force acting on the block is its weight, which can be divided into two components: one perpendicular to the surface and one parallel to the surface. The component perpendicular to the surface is counteracted by the normal force from the surface, so it does not contribute to the acceleration. The component parallel to the surface is what causes the block to accelerate.

The weight of the block can be calculated using the equation:

Weight = mass * acceleration due to gravity

W = m * g

where W is the weight, m is the mass, and g is the acceleration due to gravity (9.8 m/s^2).

In this case, the weight acting parallel to the surface can be calculated by multiplying the weight of the block by the sine of the angle:

Weight parallel = Weight * sin(θ)

where θ is the angle of inclination (12°).

Now we can find the acceleration by using Newton's second law:

Net force = Weight parallel = mass * acceleration

Weight parallel = m * g * sin(θ)

Therefore,

acceleration = (m * g * sin(θ)) / m

Since the mass of the block cancels out, the acceleration is independent of the mass of the block.

Plugging in the values:

acceleration = (6.0 kg) * (9.8 m/s^2) * sin(12°)

Calculating this value gives us:

acceleration ≈ 1.22 m/s^2

Therefore, the acceleration of the block, ignoring any friction, is approximately 1.22 m/s^2.

To find the acceleration of the block, we need to analyze the forces acting on it.

First, we need to identify the gravitational force acting on the block. The force due to gravity can be calculated using the formula:

Force_gravity = mass * acceleration_gravity

where mass is the mass of the block and acceleration_gravity is the acceleration due to gravity (9.8 m/s²).

Force_gravity = 6.0 kg * 9.8 m/s²
Force_gravity = 58.8 N

Next, we need to resolve the force due to gravity into two components: one parallel to the surface and one perpendicular to the surface. The component of the gravitational force parallel to the surface is responsible for the acceleration of the block.

The parallel component of the gravitational force can be calculated using the formula:

Force_parallel = Force_gravity * sin(θ)

where θ is the angle of tilt. In this case, θ = 12°.

Force_parallel = 58.8 N * sin(12°)
Force_parallel = 12.15 N

Finally, we can calculate the acceleration of the block by using Newton's second law:

Acceleration = Force_parallel / mass

Acceleration = 12.15 N / 6.0 kg
Acceleration ≈ 2.02 m/s²

Therefore, the acceleration of the block (ignoring friction) is approximately 2.02 m/s².
