Answer:
The answer is simple machine!!
Answer:
Angular acceleration = 5 rad /s ^2
Kinetic energy = 0.391 J
Work done = 0.391 J
P =6.25 W
Explanation:
The torque is given as moment of inertia × angular acceleration
angular acceleration = torque/ moment of inertia
= 10/2= 5 rad/ s^2
The kinetic energy is = 1/2 Iw^2
w = angular acceleration/time
=5/8= 0.625 rad /s
1/2 × 2× 0.625^2
=0.391 J
The work done is equal to the kinetic energy of the motor at this time
W= 0.391 J
The average power is = torque × angular speed
= 10× 0.625
P = 6.25 W
Answer:
The final velocity of the plane is 100 m/s.
Explanation:
To solve this problem, we will use one the kinematics equations. First, let's write out what information we have given and what we are trying to find.
x = 5.0 * 10^2 m
a = 5.0 m/s^2
v1 = 0 m/s (starts from rest)
v2 = ? (we are trying to find the final velocity)
Using the variables listed above, we can select the following equation to use:
v2^2 = v1^2 + 2ax
Now, we should plug in our known values and isolate the unknown variable.
v2^2 = 0 + 2(10)(500)
To solve for the velocity, we should take the square root of both sides of the equation to get rid of the square on the left side of the equation.
v = sqrt(10,000)
Now, we must simplify the right side of the equation to solve for v (the unknown variable).
v = 100 m/s
Therefore, your answer is 100 m/s.
Hope this helps!
