Q1.) A. 12
Q2.) A.
Q3.) C. A probability near 1 indicates a likely event
Q4.) D. 5
For this case we have the following equation:
w = || F || • || PQ || costheta
Where,
|| F ||: force vector module
|| PQ ||: distance module
costheta: cosine of the angle between the force vector and the distance vector.
Substituting values:
w = (60) * (100) * (cos (45))
w = 4242.640687 lb.ft
Answer:
The work done pushing the lawn mower is:
w = 4242.640687 lb.ft
X+3 or x-8
These answers will both work!
