         Force = (mass) x (acceleration)

           5 N  =  (9 kg) x (acceleration)

Divide each side
by  9 kg :              5 N / 9 kg  =  acceleration

                           Acceleration = (5/9)  kg-meter/sec²-kg

                                             =  0.555...  m/s²   .

The Iceberg Kid, infamous for imposing a deep freeze on whoever disagrees with him, discovers that in his advanced teenaged year
Mademuasel [1]

Answer:

7.24 Ω

Explanation:

Power = energy / time = 195 J / 9.81 = 19.88 W

and power = V² / R

R  resistance = 12 V²  / 19.88 W  = 7.24 Ω

A ball is hit with a paddle, causing it to travel straight upward. It takes 2.90 s for the ball to reach its maximum height afte
zmey [24]

Answer:

A. 28.42 m/s

B. 41.21 m

Explanation:

From the question given above, the following data were obtained:

Time (t) to reach the maximum height = 2.90 s

Initial velocity (u) =?

Maximum height (h) =?

A. Determination of the initial velocity of the ball.

Time (t) to reach the maximum height = 2.90 s

Final velocity (v) = 0 m/s (at maximum height)

Acceleration due to gravity (g) = 9.8 m/s²

Initial velocity (u) =?

v = u – gt (since the ball is going against gravity)

0 = u – (9.8 × 2.9)

0 = u – 28.42

Collect like terms

0 + 28.42 = u

u = 28.42 m/s

Thus, the initial velocity of the ball is 28.42 m/s

B. Determination of the maximum height reached by the ball.

Final velocity (v) = 0 m/s (at maximum height)

Acceleration due to gravity (g) = 9.8 m/s²

Initial velocity (u) = 28.42 m/s

Maximum height (h) =?

v² = u² – 2gh (since the ball is going against gravity)

0² = 28.42² – (2 × 9.8 × h)

0 = 807.6964 – 19.6h

Collect like terms

0 – 807.6964 = – 19.6h

– 807.6964 = – 19.6h

Divide both side by – 19.6

h = – 807.6964 / – 19.6

h = 41.21 m

Thus, the maximum height reached by the ball is 41.21 m

What Is meant By MA of a machine is 2?​
stich3 [128]

Answer:

See below ~

Explanation:

The Mechanical Advantage (MA) is defined as the ratio between the force produced by the machine to the force applied to it.

=============================================================

So,

⇒ \frac{F(out)}{F(in)} = 2

⇒ This means that the force produced is twice the applied force

A 6.0 kg bowling ball moving at 3.5m/s to the right makes a collision, head-on, with a stationary 0.70 kg bowling pin. If the ba
devlian [24]

Answer:

The velocity of the pin will be 6.26 m/s in the right direction.

Explanation:

Let's use the momentum conservation equation.

p_{i}=p_{f}

Initially, we have:

p_{i}=m_{b}*v_{ib}

Where:

  • m(b) is the ball mass
  • v(ib) is the initial velocity of the ball

Now, the final momentum will be:

p_{f}=m_{b}*v_{fb}+m_{p}*v_{fp}

Where:

  • m(p) is the pin mass
  • v(fb) is the final velocity of the ball
  • v(fp) is the final velocity of the pin

Then, using the equation of the conservation we have:

m_{b}*v_{ib}=m_{b}*v_{fb}+m_{p}*v_{fp}

6*3.5=6*2.77+0.7*v_{fp}

6*3.5=6*2.77+0.7*v_{fp}

v_{fp}=6.26 m/s

Therefore the velocity of the pin will be 6.26 m/s in the right direction.

I hope it helps you!
