Answer:
T =176 N
Explanation:
from diagram
F -(m_1+m_2_g) = (m_1+m_2_g)a
440 - (6+4)g = (6+4)a
a =\frac{440-10*9.8}{10}
a =34.2 m/s^2
frrom free body diagram of mass m2 = 4kg
T -m_2g =m_2a
T = m_2(g +a)
T = 4(9.81+34.2)
T =176 N
Answer:
19.0 m/s
Explanation:
First of all, we can find the acceleration of the object by using Newton's second law:
where
F = 200 N is the net force applied to the object
m = 50.0 kg is the mass of the object
a is the acceleration
Solving for a,
Now we can find the final speed of the object:
where
u = 3.0 m/s is the initial speed
a = 4.0 m/s^2 is the acceleration
t = 4.0 s is the time
Substituting,
The waste management and food and drink packages are being designed to combat the challenge to reusing the waste and reccycle the waste. Tremendous researches are being carried out to find out less polluting or non polluting labels and other materials, which can be easily recycled.
Answer:
Explanation:
Let the length of the board is L
now if its base is of length 10 feet
and it makes and angle of 35 degree with the ground
so here the horizontal component of the length of the board must be equal to the base
Answer: Newton, the unit of force, is defined based on Newton's Second Law (F=ma), as the force required to give a mass of one kilogram an acceleration of 1 meter/second2. Thus, it is derived from these other units.
