If you were to suspend a baseball bat from one end and let it swing back and forth, does it make a simple pendulum?
Ok I think it doesn't because a baseball bat's upper portion(bat head) weighs more than the bottom so I figure that it will stop after one swing instead of swaying back and...
A wrecking ball is suspended from a crane by a cable that is 30 m long. How much time is required for such a simple pendulum to make one complete oscillation? no picture was given to me
Ok this is a pendulum problem and its asking for time which is the period.
So I think that this formula...
Ok here is the correct solution.
k=mg/x
k= (.1kg)(9.81)/.02m
k= 49.1 N/m
so I got the correct answer by using hooke's law?
Now that I got that then for part b it asks:
How much force wil cause the spring to compress by 0.5 cm?
F=-kx
So the answer is
F=...
A mass of 100 g causes a vertical spring to stretch by 2.0 cm. a) find the spring constant of the spring in N/m: No picture was given to me.
Ok I am not sure if this is the formula to find spring constant so is it:
k= mg/x
and if so the answer is
k=(100)(9.81)/2.0 cm
k= 490.5 N/m...
A 10 kg mass is traveling along a track at 3 m/sec. It enters a circular region of radius 3m.
1. what is its speed at the bottom of the circular region?( I got 12 m/s)
2. what is the normal force at the bottom?( I got 52 N)
Right or wrong and if wrong what's the correct...
Ok I am new this forum so hello to all. Here is the problem that I've been working on. Is this right or wrong and what is the right answer?
Two blocks are connected by a rope that wraps around a pulley. A force of 50 N acts on the 5 kg mass at an angle of 36 degrees.
1. what is the...
