The position-time equation for a certain train is

astraxan [27]

Answer:

$a=4.8m/s^2$

Explanation:

Hello,

In this case, since the acceleration in terms of position is defined as its second derivative:

$a=\frac{d^2x(t)}{dt^2}=\frac{d^2}{dt^2}(2.9+8.8t+2.4t^2)$

The purpose here is derive x(t) twice as follows:

$a=\frac{d^2x(t)}{dt^2}=\frac{d}{dt}(8.8+2*2.4*t)\\ \\a=4.8m/s^2$

Thus, the acceleration turns out 4.8 meters per squared seconds.

Best regards.

Block 2 of mass 1.00 kg is at rest on a frictionless surface and touching the end of an unstretched spring of spring constant 20

son4ous [18]

Answer:

x = 0.327 m

Explanation:

Block 2 of mass 1.00 kg is at rest

spring constant = 200 N/m

Block 1 of mass 2 kg moving at 4 m/s

m₁ v₁ = (m₁ + m₂)V

2 x 4 = (2 + 1) V

V = 2.67 m/s

loss of kinetic energy = gain elastic potential energy

$\dfrac{1}{2}mv^2 = \dfrac{1}{2}kx^2$

$\dfrac{1}{2}\times (3)\times 2.67^2 = \dfrac{1}{2}\times 200 \times x^2$

x = 0.327 m

hence, the spring compressed distance is equal to x = 0.327 m

The left ventricle of the heart accelerates blood from rest to a velocity of 26 cm/s. (a) If the displacement of the blood durin

pentagon [3]

Explanation:

Initial speed of blood, u = 0

Final speed of the blood, v = 26 cm/s

(a) Displacement of the blood, d = 2 cm

Let a be its acceleration. It can be calculated using third equation of motion as :

$a=\dfrac{v^2-u^2}{2s}$

$a=\dfrac{(26)^2}{2\times 2}$

$a=169\ cm/s^2$

(b) Let t is the time taken by the blood to reach its final speed. It can be calculated as :

<u> $t=\dfrac{v-u}{a}$ </u>

$t=\dfrac{26\ cm/s}{169\ cm/s^2}$

t = 0.15 s

Hence, this is the required solution.
