Net force = (mass) x (acceleration) . . . . that's Newton's 2nd law of motion
Net force = (15 kg) x (10 m/s²)
<em>Net force = 150 Newtons</em>
Answer:
19,224 N
Explanation:
The given parameters are;
The mass limit of the elevator = 2,400 kg
The maximum ascent speed = 18.0 m/s
The maximum descent speed = 10.0 m/s
The maximum acceleration = 1.80 m/s²
Given that the acceleration due to gravity, g ≈ 9.81 m/s²
The minimum upward force that the elevator cable exert on the elevator car,
, is given in the downward motion as follows;
= m·g - m·a
∴
= 2,400 kg × 9.81 m/s² - 2,400 kg × 1.80 m/s² = 19,224 N
The minimum upward force that the elevator cable exert on the elevator car,
= 19,224 N
Let the moving object be object 1 and the stationary object be object 2.
Momentum of object 1 before collision = 55 kg*m/s
Momentum of object 2 before collision = 0 kg*m/s
Momentum of object 1 after collision = 13 kg*m/s
According to the law of conservation of momentum, the sum of the momenta of 2 objects remains the same even after collision. So,
Momentum of object 1 before collision + momentum of object 2 before collision = Momentum of object 1 after collision + momentum of object 2 after collision
55 + 0 = 13 + momentum of object 2 after collision
Momentum of object 2 after collision = 55 - 13 = 42 kg*m/s
Hope I helped!
Spectrum can can different meaning depending on the specific situation. But overall, a spectrum is a large amount of or infinite collection of values that exist withing a certain range. For example, light wavelengths exist on a spectrum becuase there are an infinite number of different wavelengths.
Hope this helps.<span />
