What is the average force on a 75 kg crash test dummy that crashes into a wall at 25 m per s and is brought to rest in 1s?
Let's use a combination of two equations F= ma and v= u + at where F= Force; m= mass; a= acceleration; v = final velocity= 0 m/s; u= initial velocity=25 m/s and t= time. From the equation v= u + at, we can solve for a. So, a = (v-u)/ t. Using F= ma F= m((v- u)/t)) F= 75kg((0-25 m/s)/ ls) F= (75 x 25) kg m/s^2 F= 1875 kg m/s^2= 1875 N
For how long should a force of 100 N act on a body of 20 kg so that it acquires a velocity of 200 ms?
u= 0 m/s v= 200 m/s m= 20 kg F= 100 N F= (mv - mu)/t 100 = (20*200 - 20*0)/t 100 = 4000/t t= 4000/100 t= 40 s hope it helps cheers ^_^
How much tension must a rope withstand if it is used to accelerate a 1900 kg car vertically upward at 0.80 ms2?
F = mg + ma F = (1200)(9.8) + (1200)(0.90) F = (1200)(9.8 + 0.9)

Complete source code for multilevel feedback scheduling?
A completed source code for multi-level feedback scheduling should contain high, normal, and low queues, as well as a queue that is to be run when the system is idle. The queues should be rotated to lower priorities once a process has been run, while the idle queue is used when no other process is being run.
