I need help with mechanics 1....Can somebody help?...
Chapter 4...
Question 7
A particle P of mass 4m kg is at rest on a horizontal table. A force of magnitude 50m Newtons acting upwards at an acute angle α to the horizontal, is applied to the particle. Given that tan α = (3/4) and that there is a resistance to the motion of magnitude 20m Newtons, find the acceleration with which P moves. Find in terms of m the magnitude of the normal contact force of the table on P.
Please help asap....
