The speed of the system when it passes through the equilibrium position is v=3.89 m/s, and this corresponds to the maximum speed of the oscillator.

The angular frequency of the oscillator is given by
\omega= \sqrt{ \frac{k}{m} }
where k is the spring constant, and m the mass. Substituting the data, we find
\omega= \sqrt{ \frac{24.3 N/m}{2.89 kg} }=2.9 s^{-1}

and since the amplitude of the oscillation, A, is related to the maximum speed by
v_{max}=\omega A
we can re-arrange this equation to calculate A:
A= \frac{v_{max}}{\omega}= \frac{3.89 m/s}{2.9 s^{-1}}=1.34 m

A car is traveling at 96km/hr. what is the acceleration of a car traveling a distance of 100m and come to rest?​
8090 [49]

Answer:

Explanation:

v² = u² + 2as

v = 0

u = 96 / 3.6 = 26.7 m/s

0² = 26.7² + 2a100

a = -3.5555555... ≈ -3.6 m/s²

the negative sign indicated the acceleration vector opposes the (assumed positive) initial velocity vector direction.

A competitive go-cart driver is traveling at a speed of 32m/s. He sees a caution flag go up and slows down at a rate of -1.5 m/s
djyliett [7]

Answer:

His final velocity is 15.8 m/s.

Step-by-step explanation:

Given:

Initial velocity of the driver is, u=32 m/s

Acceleration of the driver is, a=-1.5 m/s²

Time taken to reach final velocity is, t=10.8 s.

The final velocity is given using the Newton's equations of motion as:

v=u+at, where, v is the final velocity.

Now, plug in the given values and solve for v.

v=32-1.5(10.8)\\v=32-16.2=15.8\textrm{ m/s}

Therefore, his final velocity is 15.8 m/s.

Ivanshal [37]

Answer:

The velocity is 60 km/hr.

Explanation:

<h3><u>Given:</u></h3>

Displacement (d) = 480 km = 48000 m

Time (t) = 8 Hours = 480 minute

Velocity (v) = ?

Now,

Velocity = Displacement ÷ Time

v = d/t

v = 480/8

v = 60 km/hr

Thus, The velocity is 60 km/hr.
