When the rocket launched the astronauts aboard experienced an acceleration of 32 m/s^2. If one of the astronauts had a mass of 6

5 kg, what net force in newtons did the astronaut experience?

Answer:

The question is somewhat vague in that acceleration is not exactly defined:

Usually a = (v2 - v1) / t    which would imply that

a = 32 / g = 32 / 9.8 = 3.27   the acceleration due to change in speed of the rocket

One can also say that the astronaut experiences an acceleration of 9.8 m/s^2 just by being motionless on the surface of the earth.

Then a = (32 - 9.8) / 9.8 = 2.27 due to the acceleration of the rocket

If we assume the first condition then

F = 65 kg * 3.27 * 9.8 m/s^2 = 2083 N

Explain why magnetic damping might not be effective on an object made of several thin conducting layers separated by insulation.
andrew-mc [135]

Answer:

The eddy currents will be very small.

Explanation:

An object made of several thin conducting layers separated by insulation may not be affected by magnetic damping because the eddy current produced in each layer due to induction will be very small and the opposing magnetic flux produced by the eddy currents will be very small.

Compare the number of electrons with the number of protons in a charged object.
svetlana [45]
If the object is negatively charged it means it has gained electron so negatively charged object has more number of electron than proton

If the object is positively charged it means it has lost electron so positively charged object has more number of proton than electron

10-kg box is sliding across an ice rink at 10 m/s . A skater exerts a constant force of 10 N against it. How long will it take f
Taya2010 [7]

Answer:

Time, t = 10 seconds

Explanation:

Given the following data;

Mass = 10kg

Force = 10N

Final velocity = 10m/s

Initial velocity = 0m/s

To find the time;

First of all, we would find the acceleration of the box.

Force = mass * acceleration

10 = 10 * acceleration

Acceleration = 10/10 = 1m/s²

Now, we can find the time by using the first equation of motion;

V = U + at

10 = 0 + 1t

10 = t

Time, t = 10 seconds

Therefore, it will take 10 seconds for the box to come to a complete stop.

A 0.10-kilogram piece of modeling clay is tossed
viva [34]

a) The initial speed of the clay is 30 m/s

b) The final velocity of the block increases (40 m/s)

Explanation:

a)

We can solve this problem by using the law of conservation of momentum. In fact, in absence of external forces (=no friction), the total momentum of the clay + block system is conserved before and after the collision. Therefore, we can write:

p_i = p_f\\m_1 u_1 + m_2 u_2 = (m_1+m_2)v  

where:  

m_1 = 0.10 kg is the mass of the clay

u_1 is the initial velocity of the clay

m_2 = 0.10 kg is the mass of the wood block

u_2 = 0 is the initial velocity of the wood block (at rest)

v = 15 m/s is the final combined velocity of the clay+block after the collision

Re-arranging the equation, we can find u_1, the speed at which the clay was tossed:

u_1 = \frac{(m_1+m_2)v-m_2 u_2}{m_1}=\frac{(0.10+0.10)(15)-0}{0.10}=30 m/s

b)

In this second case, the clay is replaced by a bouncy ball, which rebounds back after the collision, instead of sticking with the block.

In this second case, the law of conservation of momentum becomes:

p_i = p_f\\m_1 u_1 + m_2 u_2 = m_1 v_1 + m_2 v_2  

where

m_1 = 0.10 kg is the mass of the ball

u_1 = 30 m/s is the initial velocity of the ball

m_2 = 0.10 kg is the mass of the wood block

u_2 = 0 is the initial velocity of the wood block (at rest)

v_1 = -10 m/s is the velocity of the bouncing ball after the collision (negative because it goes backward)

v_2 is the velocity of the block after the collision

Solving for v_2, we find the final velocity of the block:

v_2 = \frac{m_1 u_1 - m_1 v_1}{m_2}=\frac{(0.10)(30)-(0.10)(-10)}{0.10}=40 m/s

As we can see, the final velocity of the block has increased. The reason for that is that, as the ball bounces back, part of the total momentum is "carried away" by the ball in the backward direction, and since the total momentum must remain constant, this means that the momentum carried by the block in the forward direction must be larger than the previous situation.
