A truck covers 40.0 m in 7.10 s while smoothly slowing down to a final velocity of 2.75 m/s.. (a) Find the truck's original spee

ser-zykov [4K]

D = vo t - at²/2
v = vo - at
40 m = vo · 7.10 - a · ( 7.10 )²/2
40 m = 7.10 vo - a· 50.41/2
40 m = 7.10 vo - 25.205 a
2.75 m/s = vo - 7.10 a ⇒ a = ( vo - 2.75 )/ 7.10
40 = 7.10 vo - 25.205 · ( vo - 2.75 ) / 7.10
40 = 7.1 vo - 3.55 vo + 9.7625
3.55 vo = 30.2375
vo = 30.2375 : 3.55 = 8.5176 m/s
Answer: the truck`s original speed is 8.5176 m/s.

A particle moves along a path described by y=Ax^3 and x = Bt, where tt is time. What are the units of A and B?

Sergeu [11.5K]

Answer:

In a nutshell, units of A and B are $\frac{1}{[l]^{2}}$ and $\frac{[l]}{[t]}$ , respectively.

Explanation:

From Dimensional Analysis we understand that $x$ and $y$ have length units ( $[l]$ ) and $t$ have time units ( $[t]$ ). Then, we get that:

$[l] = A\cdot [l]^{3}$ (Eq. 1)

$[l] = B\cdot [t]$ (Eq. 2)

Now we finally clear each constant:

$A = \frac{[l]}{[l]^{3}}$

$A = \frac{1}{[l]^{2}}$

$B = \frac{[l]}{[t]}$

In a nutshell, units of A and B are $\frac{1}{[l]^{2}}$ and $\frac{[l]}{[t]}$ , respectively.
