Answer:2538.43 N
Explanation:
Given
Mass of Log=205 kg
Ramp angle
Coefficient of Friction=0.855
log acceleration
Let T be the Tension

Here 

T=849.04+132.63+1556.76=2538.435 N
Answer:
a= 2.667 m/s²
Explanation:
Given that
Initial velocity ,u= 2 m/s
Final velocity ,v= 10 m/s
Time taken ,t= 3 s
As we know that
v = u + at
a=Acceleration ,u=Initial velocity ,v= Final velocity ,t=time
Now by putting the values in the above equation
v = u + at
10 = 2 + a x 3
8 = 3 a

a= 2.667 m/s²
Therefore the acceleration of the biker will be 2.667 m/s²
Answer:
2/3
Explanation:
It is important to bear in mind that momentum is generated by the fluid. Momentum is proportional to the mass and velocity, therefore increasing the mass(density) of the liquid by a factor of 2, while the velocity is constant, increases the momentum of fluid (and rocket) by 2. For any closed system, the momentum is conserved. With that in mind, the momentum of the fluid is equal to but opposite in direction to the momentum of the rocket. Velocity of the rocket given by v=p/m (Where p=momentum of the rocket initially and m is its initial mass). The mass of the rocket increases 3 times. So....
Initially:
vi=p/m
Now:
vf=2p/3m
<h3>The ratio is given by:</h3>
vf:vi = 2p/3m:p/m
Waves are either transversal stereotypical pictures of waves or longitudinal it goes in rings waves are just different forms of vibration of any kind of energy
