A transverse sinusoidal wave on a string has a period T = 25.0 ms and travels in the negative x direction with a speed of 30.0 m

/s . At t=0, an element of the string at x = 0 has a transverse position of 2.00 cm and is traveling downward with a speed of 2.00 m/s.(a) What is the amplitude of the wave?

The amplitude of the wave is determined as 0.0215 m.

<h3>What is amplitude of a wave?</h3>

The amplitude of a wave is the maximum displacement of the wave.

The amplitude of the wave is calculated as follows;

<h3>Amplitude of the wave</h3>

A cos(Φ) = 0.02 ---- (1)

-80π A sin(Φ) = - 2

A sin(Φ) = 1/40π  ----- (2)

Divide (2) by (1)

tan(Φ) = 1/(0.02 x 40π)

tan(Φ) = 1/(0.8π)

Ф = tan⁻¹( 1/(0.8π))

Ф = 0.3787

A cos (0.3787) = 0.02

A (0.929) = 0.02

A = 0.0215 m

Thus, the amplitude of the wave is determined as 0.0215 m

with what speed does a freely falling object dropped from a height of 88.2m hit the ground? how long does it take for it hit the
maria [59]

Answer:

Vf = 41.6 [m/s]

Explanation:

To solve this problem we must use the equations of kinematics.

Vf² = Vo² + (2*g*y)

where:

Vf =  final velocity [m/s]

Vo = initial velocity = 0

g = gravity acceleration = 9.81 [m/s²]

y = height = 88.2 [m]

Note: The positive sign of the equation tells us that the acceleration of gravity goes in the direction of motion.

Vf² = Vo² + (2*g*y)

Vf² = 0 + (2*9.81*88.2)

Vf = (1730.48)^0.5

Vf = 41.6 [m/s]

If a projectile travels in the air for 8 seconds when does a projectile reach its highest point
emmainna [20.7K]

Given

The projectile is in air for a time of t=8 sec

To find

The time it takes to reach the highest point

Explanation

A projectile moves up to the highest point and then again moves down following a parabolic path.

So it will reach the highest point at a time half the time it requires to follow teh parabolic path.

The time taken to reach the highest point is 4 sec

Conclusion

The time taken is 4 sec.
