Answer:

O - A : acceleration

A - B : zero acceleration

B - C : deceleration

C - S : zero velocity

Explanation:

acceleration is velocity over time, meaning that the slope of the graph is showing acceleration

Answer / Explanation:

acceleration is essentially increasing in velocity. [acceleration is literally velocity over time]

So, we can see acceleration on this velocity/time graph (the y-axis is representative of velocity).

Meaning that...

When we increase in velocity, that is acceleration. [A]

When we stay at the same velocity, that is zero acceleration. [B]

<em>> (we are not increasing {acceleration} or decreasing {deceleration} in velocity/ acceleration over time)</em>

When we decrease in velocity, that is deceleration. [C]

When we have <em>no</em> velocity (velocity = 0), that is zero velocity. [D]

So, this curve is already in order of A-B-C-D.

(origin/0 to A = acceleration)

(A to B = zero acceleration)

(B to C = deceleration)

(C to S = zero velocity)

hope this helps!!

A trolley is moving at constant speed in a friction compensated track. Some plasticine is dropped on the trolley and sticks on i

Maurinko [17]

Answer:

Since the momentum of the body remains constant ( conserved) the trolley slows down (its velocity reduces) since its mass increases.

A NASA satellite has just observed an asteroid that is on a collision course with the Earth. The asteroid has an estimated mass,

Citrus2011 [14]

Answer:

v = 7934.2 m/s

Explanation:

Here the total energy of the Asteroid and the Earth system will remains conserved

So we will have

$-\frac{GMm}{r} + \frac{1}{2}mv_0^2 = -\frac{GMm}{R} + \frac{1}{2}mv^2$

now we know that

$v_0 = 660 m/s$

$M = 5.98 \times 10^{24} kg$

$m = 5 \times 10^9 kg$

$r = 4 \times 10^9 m$

$R = 6.37 \times 10^6 m$

now from above formula

$GMm(\frac{1}{R} - \frac{1}{r}) + \frac{1}{2}mv_0^2 = \frac{1}{2}mv^2$

now we have

$2GM(\frac{1}{R} - \frac{1}{r}) + v_0^2 = v^2$

now plug in all data

$2(6.67 \times 10^{-11})(5.98 \times 10^{24})(\frac{1}{6.37 \times 10^6} - \frac{1}{4 \times 10^9}) + (660)^2 = v^2$

$v = 7934.2 m/s$

The space probe Deep Space 1 was launched on October 24th, 1998 and it used a type of engine called an ion propulsion drive. An

Xelga [282]

Answer:

Explanation:

mass of probe m = 474 Kg

initial speed u = 275 m /s

force acting on it F = 5.6 x 10⁻² N

displacement s = 2.42 x 10⁹ m

A )

initial kinetic energy = 1/2 m u² , m is mass of probe.

= .5 x 474 x 275²

= 17923125 J

B )

work done by engine

= force x displacement

= 5.6 x 10⁻² x 2.42 x 10⁹

= 13.55 x 10⁷ J

C ) Final kinetic energy

= Initial K E + work done by force on it

= 17923125 +13.55 x 10⁷

= 1.79 x 10⁷ + 13.55 x 10⁷

= 15.34 x 10⁷ J

D ) If v be its velocity

1/2 m v² = 15.34 x 10⁷

1/2 x 474 x v² = 15.34 x 10⁷

v² = 64.72 x 10⁴

v = 8.04 x 10² m /s

= 804 m /s

what output force is generated when an input force of 630 n is applied to a machine with a mechanical advantage of 3

Marta_Voda [28]

The mechanical advantage is the factor by which
the machine multiplies the input force.

If the MA is 3 and the input force is 630N, then
the output force is

(3) x (630N) = 1,890N
