Question

Q - A force of 25 Newton is required to pull up a block of mass 4 kg along an inclined plane making an angle of 30° with the horizontal. If the block is moved through a distance of 10 m along the inclined plane as shown in the figure. (a) Calculate the work done by the force in pulling the block. (b) Calculate the work done against the force gravity (g= 10 m sec to the power minus 2 )

Answer 1

Answer:

Explanation:hello mate.. Here angle of repose α=tan −1 (μ s )α=tan −1 ( 21 )=30 0 The angle of inclination is greater than the angle of respose. ...
