(a) is the vertical direction, the force of gravity
on the object (or the wight force: w = Mg ) pulls the crate down while the surface reaction. N. pushes it 103N
rd, as shown:
w = Mg = (20.0kg 9.8m s3 - 196N
N- 196N as well
(b) In the horizontal direction, in the absence of
friction, there are two forces: (F) and the 53-N force. Applying the Newton's 2nd law helps the calculation of the unknown force. F. F - 53N (20.0 kg)(2.5 m 3
