A 180-g block is pressed against a spring of force constant 1.35 kN/m until the block compresses the spring 10.0 cm. The spring

rests at the bottom of a ramp inclined at 60.0° to the horizontal. Using energy considerations, determine how far up the incline the block moves from its initial position before it stops under the following conditions.

Answer:

L = 4.32 m

Explanation:

Here we can use the energy conservation to find the distance that it will move

As per energy conservation we can say that the energy stored in the spring = gravitational potential energy

\frac{1}{2}kx^2 = mg(L + x)sin\theta

\frac{1}{2}(1.35 \times 10^3)(0.10^2) = (0.180)(9.8)(L + 0.10)sin60

now we need to solve above equation for length L

6.75 = 1.53(L + 0.10)

L + 0.10 = 4.42

L = 4.42 - 0.10

L = 4.32 m

At TTT = 14 ∘C∘C, how long must an open organ pipe be to have a fundamental frequency of 262 HzHz ? The speed of sound in air is
Stolb23 [73]

Answer:

Length of pipe organ(L) = 0647 m (Approx)

Explanation:

Given:

Temperature (T) = 14°C

Fundamental frequency (F) = 262 Hz

Speed of sound (v) = 331 + 0.60(T) m/s

Find:

Length of pipe organ(L)

Computation:

Speed of sound (v) = 331 + 0.60(14) m/s

Speed of sound (v) = 339.4

Length of pipe organ(L) = Speed of sound (v) / 2(Fundamental frequency)

Length of pipe organ(L) = 339.4 / 2 (262)

Length of pipe organ(L) = 0647 m (Approx)

What is the change in the ball's position from t=0s to t=1.0s? express your answer using two significant figures?
Damm [24]
The change in position is the change of the position of the ball from initial to final. In this problem, we are given the initial position of the ball which is t=0s and the final position which is t=1.0s. Thus, the change in the ball's position from 0 to 1 second is 4.0 m
