Answer:

$a= 0.2 m/s^2\\s = 20m\\t = 2 s$

Explanation:

gievn

two forces are given

$f_{1} = 2000 N \\f_{2} = 1800 N\\F_{net} = 2000 -1800 = 200N$

A) (a) What is the acceleration of the 1000-kg boat?

$f_{net} = ma\\a = \frac{f_{net}}{m}$

$a = \frac{200}{1000}\\a= 0.2 m/s^2$

B) If it starts from rest, how far will it move in 10.0 s?

using kinematic equation

$s = ut +\frac{1}{2}at^2\\ u = 0 \ m/s\\\\S = \frac{1}{2} at^2 \\s = \frac{1}{2} \times 0.2 \times (10)^2\\s = 10 m$

(c) What will its velocity be at the end of this time?

$v= u +at \\u = 0 m/s \\v = 0.2\times 10\\v = 2 m/s$

An object rotates about a fixed axis, and the angular position of a reference line on the object is given by θ = 0.220e3t, where

OLga [1]

Answer: $a_{t}=3.96$

$a_{c}=0.8712$

Explanation:

Given

$\theta =0.220e^{3t}$

r=2cm

Now angular velocity is given by $\omega =\frac{\mathrm{d}\theta}{\mathrm{d}t}$

$\omega =0.66e^{3t}$

Now linear velocity(v) is given = $\omega r$

$v=1.32e^{3t}$

Now tangential component of acceleration is given by

$a_{t}=\frac{\mathrm{d}\vec{v}}{\mathrm{d}t}=3.96e^{3t}$

at t=0

$a_{t}=3.96cm/s^2$

radial component of acceleration is given by

$a_{c}=\omega ^{2}r$

$a_{c}=0.4356e^{6t}\times 2$

$a_{c}=0.8712e^{6t} cm/s^{2}$

at t=0

$a_c=0.8712 cm/s^{2}$

Find the acute angles between the curves at their points of intersection. (The angle between two curves is the angle between the

ladessa [460]

Answer:

1.190390345 degrees.

Explanation:

As stated in the problem that the angle between the two curves is also the angle between slopes of the two cures at the point of intersection, which is 1 (when we set two equation equal and solve for x).

We know, if you don't you could verify it for yourself and it will be a nice mathematical exercise for you, that when there are two lines with slopes $m_1$ and $m_2$ then the angle between them and their two slopes has following relationship.

$tan(\alpha ) = |\frac{m_2-m_1}{1+m_1m_2}|$ where $\alpha$ is angle between the two lines.

As it is clear that we can easily get the angle between the two curves if we know slopes at that point, which you will see in second is very straight forward to calculate.

Slopes are simply derivatives evaluated at the point of intersection and the two derivatives are $D_1$ 16x and $D_2 =24x^2$ , substituting x =1 we get, $m_1 = 16$ and $m_2 = 24$ .
