If x =(20-4t^2) find average velocity between t=0and t=2sec

lapo4ka [179]

Answer:

The average velocity is 8 unit per sec

Explanation:

Given as :

The Distance x = 20 - 4t² unit

Change in time Δt = ( 2 - 0 ) s = 2 s

Let the velocity = V unit/s

∴ V = $\frac{\partial (20 - 4t^{2})}{\partial x}$

Or, V = - 8t unit/s

Now velocity at t = 0

V1 = - 8 × 0 = 0 unit/s

And velocity at t = 2 sec

V2 = - 8 × 2 = - 16

So, Average velocity = $\frac{v2 - v1}{2}$ = $\frac{- 16 - 0}{2}$ = -8

Or, $\begin{vmatrix}V\end{vmatrix}$ = 8 unit/sec

Hence The average velocity is 8 unit per sec Answer

A 1.5kg mass attached to an ideal spring oscillates horizontally with an amplitude of 0.50m. The spring constant is 85 n/m. what

Stolb23 [73]

Answer:

frequency of the mass motion $f$ ≅ 1.2 Hz

Explanation:

Given that:

Mass m = 1.5 kg

Amplitude A = 0.50 m

Spring constant k = 85 n/m

The frequency can be calculated by using the formula:

$f = \frac{1}{2 \pi} \sqrt{\frac{k}{m} }$

$f = \frac{1}{2 \pi} \sqrt{\frac{85}{1.5} }$

$f = 1.198$ Hz

frequency of the mass motion $f$ ≅ 1.2 Hz
