Question

50 POINTS FOR ANSWER!!!!!!!!!!!!!!!!!!!!!!

Answer 1

1) force to pull it up 0.8 m
= 101.93 * 0.8
= 81.54 N
2) force for horizontal displacement
which can be found out by subtracting above value from total force applied
= 200-101.93
=98.07

Now finding horizontal displacement
98.07 = 101.93 * d
d= 0.96 m
Now since we found out hori. and vertical dist. apply Pythagoras theorem to find out length of ramp.

l^2= 0.96 ^2 + 0.8 ^2
= 0.9216 + 0.64
= 1.56

L = 1.25 m approx.
