You are watching an object that is moving in shm. when the object is displaced 0.600 m to the right of its equilibrium position,

it has a velocity of 2.20 m>s to the right and an acceleration of 8.40 m>s 2 to the left. how much farther from this point will the object move before it stops momentarily and then starts to move back to the left?

The work that Sam should do in order to stop is the boat is the same as that of the kinetic energy of the object in order to counter its motion. Kinetic energy is calculated through the equation,
                           KE = 0.5mv²
where KE is kinetic energy, m is mass, and v is the velocity.
Substituting,
                         KE = 0.5(1200kg)(1.2 m/s)²
                            <em>KE = 864 J</em>

A 20.0-kg rock is sliding on a rough, horizontal surface at 8.00 m/s and eventually stops due to friction. The coefficient of ki
Neporo4naja [7]

Answer:

a = -1.961\,\frac{m}{s^{2}}, s = 16.318\,m, t = 4.079\,s

Explanation:

The equations of equilibrium for the rock are:

\Sigma F_{x} = -\mu_{k}\cdot N = m \cdot a

\Sigma F_{y} = N - m\cdot g = 0

After some algebraic handling, the following expression is found:

-\mu_{k}\cdot m \cdot g = m \cdot a

-\mu_{k}\cdot g = a

Deceleration experimented by the rock is:

a = - (0.2)\cdot (9.807\,\frac{m}{s^{2}} )

a = -1.961\,\frac{m}{s^{2}}

The distance travelled by the rock before stopping is:

s = \frac{(0\,\frac{m}{s} )^{2}-(8\,\frac{m}{s} )^{2}}{2\cdot (-1.961\,\frac{m}{s^{2}} )}

s = 16.318\,m

And the time is:

t = \frac{0\,\frac{m}{s}-8\,\frac{m}{s}}{(-1.961\,\frac{m}{s^{2}} )}

t = 4.079\,s

1. If a 25 kg car accelerates at a speed of 100m/s2,2 what will the force of the car be?
algol13

Answer:

F = 2500N

Explanation:

F = ma

You're given m=25kg and a=100m/s²

Plug it in

F = (25)(100)

F = 2500N
