Answer:
F = 153637 lb
Explanation:
Let's use the kinematic equations to find the airplane's braking speed
v² = v₀² + 2 a d
The final speed is zero
a = - v₀² / 2d
Let's reduce the magnitudes
v₀ = 110 mi / h (5280 ft / 1 mile) (1 h / 360 s) = 161.33 ft / s
a = -161.33²/2 90
a = -144.60 ft / s²
Now we can use Newton's second law to find the tension
F = m a
F = (34000/32) 144.60
F = 153637 lb
Fluid clutches are used on equipment that is subjected to higher torque per unit volume. This type of clutch makes use of an incompressible fluid like oil in order to transfer the input of a movement from a pedal and cylinder to an actuating cylinder. Releasing the this clutch would stop the transfer of power but still allowing the engine to turn continuously.

- Initial velocity,u = -2 m/s
- Final velocity,v = -10 m/s
- Time taken, t = 4 seconds
Find the acceleration ( a ) .
We know that,
Substituting the values in the above formula, we get
Hence,the acceleration of a body is -2 m/s².
