Answer:
The helicopter was 1103.63 meters high when the package was dropped.
Explanation:
We consider positive speed as a downward movement
y: height (m)
t: time (s)
v₀: initial speed (m/s)
Δy = v₀t + 
gt²
Δy= 15
×15 s + ×9.81
×(15 s)²
Δy= 1103.63 m
Answer:
2.5m
Explanation:
Torque is defined as the rotational effect of a force on a body.
The torque T for the maximum shear stress is given as 0.1 Nm
Frictional torque is the torque caused by a frictional force
The frictional torque F is given as 0.04 Nm/m
The maximum length of the shaft is thus given as
L = T / F
= 0.1/0.04
L= 2.5 m
Answer:
if no mistaken then it is 300kN
Explanation:
Using SI units (the default if a system is not specified) 200T = 200000kg as the mass of the whale, it would weigh 1960kN in 1g Earth gravity.
On the Moon, the acceleration is 0.166g, to it would weigh about 330kN.
Answer:
Explanation:
<u>Centripetal Acceleration</u>
It's the acceleration that an object has when traveling on a circular path to take into consideration the constant change of velocity it must have in order to keep going in the circular path.
Being v the tangent speed, and r the radius of curvature of the circle, then the centripetal acceleration is given by
We can compute the value of v by using the distance and the time taken to travel:
Now we calculate the centripetal acceleration
The Y-component of the vector is 34.65 m.
<h3>What is a vector?</h3>
Vectors are quantities that have both magnitude and direction.
The Y-component of the vector can be calculated using the formula below.
Formula:
- Y = rsin∅............. Equation 1
Where:
- Y = Y-component of the vector
- r = magnitude of the vector
- ∅ = angle of the vector to the horizontal.
From the question,
Given:
Substitute these given values into equation 1
- Y = 82(sin25°)
- Y = 34.65 m
Hence, The Y-component of the vector is 34.65 m.
