Question #9799

derive equation of motion for uniformly accelerated .what will be its speed at the end of 100s?

Expert's answer

s=s

if we derive this equation we'll get

v=v

So if we need to know the speed when t=100s we substitute t=100 into the last equation and obtain

v=v

_{0}+v_{0}t+at^{2}/2 whete s_{0}-initial displacement, v_{0}-initial velosity, a=const - accelerationif we derive this equation we'll get

v=v

_{0}+atSo if we need to know the speed when t=100s we substitute t=100 into the last equation and obtain

v=v

_{0}+100a
