Pulling Force= 131cos27
Friction Force= 0.125(18x9.8-131sin27)
Pulling Force-Friction Force= 18a
(solve for a)
Vf^2=Vi^2+2ad
(solve for Vf)
A 18 kg block is dragged over a rough, hor- izontal surface by a constant force of 131 N acting at an angle of 27 ◦ above the horizon- tal. The block is displaced 15 . 7 m, and the coefficient of kinetic friction is 0 . 125. The acceleration of gravity is 9 . 8 m / s 2 .If the block was originally at rest, determine its final speed. Answer in units of m / s.

On a horizontal smooth surface, 2 kg block is placed castward and 4 kg block is placed westward. Two blocks are now connected with a horizon tal string. If 12 N horizontal force is applied on 4 kg block along west direction, find (i) common acceleration of two blocks. (1) tension in the string.
