A 5.0‑kg block is pulled up a smooth incline that makes an angle of \(30^{\circ}\) with the horizontal. The length of the incline is \(10\ \text{m}\). The coefficient of kinetic friction between the block and the incline is \(0.20\). The block moves up the incline at constant speed and takes \(8\ \text{s}\) to travel the length of the incline. (a) Find the magnitude of the pulling force required, (b) calculate the work done by this force, and (c) determine the power output of the pulling force.

Answer Options

A. a) \(40.0\ \text{N}\), b) \(400\ \text{J}\), c) \(50\ \text{W}\)
Correct Answer B. a) \(33.0\ \text{N}\), b) \(330\ \text{J}\), c) \(41\ \text{W}\)
C. a) \(35.0\ \text{N}\), b) \(350\ \text{J}\), c) \(44\ \text{W}\)
D. a) \(30.0\ \text{N}\), b) \(300\ \text{J}\), c) \(38\ \text{W}\)
Correct Answer
B
Correct Option:
a) \(33.0\ \text{N}\), b) \(330\ \text{J}\), c) \(41\ \text{W}\)
