An object is on a frictionless inclined plane. The plane is inclined at an angle of 30° with the horizontal. What is the object's acceleration.

Answer 1

The acceleration of the object on a frictionless inclined plane can be calculated using the following equation:

a = g*sin(θ)

Where:
a = acceleration
g = acceleration due to gravity (9.8 m/s^2)
θ = angle of inclination (30° in this case)

Plugging in the values:

a = 9.8 m/s^2 * sin(30°)
a = 9.8 m/s^2 * 0.5
a = 4.9 m/s^2

Therefore, the acceleration of the object on the frictionless inclined plane is 4.9 m/s^2.
