A block of mas 2.0 kg is pulled up on a smooth incline of angle `30^0` with the horizontal. If the block moves wth an acceleration of `1.0 m/s^2`, find the power delivered by the pulling force at a time 4.0 s after the motion starts. What is the average power delivered during the 4.0 s after the motion starts?

Explanation

To solve the problem step by step, we will break it down into parts to find the power delivered by the pulling force at a time of 4.0 seconds after the motion starts, and then calculate the average power delivered during that time.

### Step 1: Identify the forces acting on the block
The block has a mass (m) of 2.0 kg and is on an incline of angle \(30^\circ\). The gravitational force acting down the incline can be calculated as:
\[ F_{\text{gravity}} = m \cdot g \cdot \sin(\theta) \]
where \( g \) is the acceleration due to gravity (approximately \(9.8 \, \text{m/s}^2\)) and \( \theta = 30^\circ \).

### Step 2: Calculate the gravitational force
