Homework Answers
(a) we need an additional mass to be hanged from the spring. The spring will be extended under the weight of hanging mass. We can measure the distance by which spring has extebded. Then we can use the following equation to find spring constant.
F = Kx
Where F = mg
So,
k = mg/x
(b) T = 2*pi sqrt (m/k)
T = 0.3974 sec
So,
f = 1/T
f = 2.5165 Hz
(C) we can use slope method.
So, place weight on slope the
We will use componenet method where
Wx = Wsin(theta)

A wooden ball with a weight of 16.0 N hangs from a string tied to a spring scale. When the ball is at rest, exactly 50% submerged in water, the spring scale reads 6.00 N. For this problem, we will use a density of water of 1000 kg/m^3, and we will use g = 10.0 m/s^2. If the ball was only 20.0% submerged in water instead, what would the spring scale read? _______ N Part (b) HomeworkUnanswered A wooden ball...

Problem 3-Under the ambient condiion, one can use the oscillation frequency of a spring-mass system to determine the mass suspended at the end of a spring using equation where f if the frequency of oscillation in the unit of s1, k is the spring constant in the unit of N/m, and m is the mass of the oscillating object in the unit of kg. The spring constant k is obtained by suspending an object of known mass mo under the...

As shown, a frictionless pulley hangs from a system of
springs and a cable. The pulley is equidistant between the two
supports attaching the springs to the ceiling. The distance between
the supports is d=1.50 m . The cable cannot stretch and its length
between the two springs is 1.8 m.

55) A 0.15-N meter stick is suspended from a spring scale at its 25-cm mark. When an object of unknown mass is hung from the meter stick on the 10-cm mark, the meter stick is in equilibrium. Draw an extended-body force diagram for the meter stick and (a) determine the mass of the object and (b) the reading on the spring scale.

A spring stretches 0.150 m when a 0.300 kg. mass is hung vertically from it. From this information you can determine the spring constant, k. Next, the spring is set up horizontally with the 0.300 kg. mass resting on a frictionless table. The block is pushed so that the spring is compressed 0.100 m from the equilibrium point, and released from rest. Determine: The spring constant k (in N/m)? The amplitude of the horizontal oscillation (in m)? The angular frequency,...
