Answer:
The power required to move each bale is 30 lbf.ft/sec.
Explanation:
F= 40lbf * sin (30º)
F=20lbf
P= F*v
P=20 lbf * 1.5 ft/sec
P= 30 lbf.ft/sec
A, B, and C are all incorrect because they are talking about springs. I'm assuming you're talking about a 2 dimensional, side to side pendulum. In that case, the answer is D because as the pendulum goes up from one side, gravity accelerates it downward until it swings to the other side. If you're not talking about this type of pendulum, leave a comment and ill come back.
Answer:
2440 N
Explanation:
As,F=m*a.....
From the question we have
force = 976 × 2.5
We have the final answer as
2440 N
