Neco 2019 Physics Question 25 diagram

A 5.0 kg block is pulled up a frictionless incline that makes an angle of \(30^{\circ}\) with the horizontal by a constant force of \(60\ \text{N}\) acting parallel to the incline. The block moves 8.0 m along the incline in 4.0 s. (i) Calculate the work done by the pulling force. (ii) Determine the increase in the block's gravitational potential energy. (iii) Find the average power supplied by the pulling force.

Answer Options

Correct Answer A. Work = 480 J, ΔU = 196 J, Power = 120 W
B. Work = 416 J, ΔU = 196 J, Power = 104 W
C. Work = 480 J, ΔU = 196 J, Power = 60 W
D. Work = 480 J, ΔU = 200 J, Power = 120 W
Correct Answer
A
Correct Option:
Work = 480 J, ΔU = 196 J, Power = 120 W
