Aperturbation in the temperature of a stream leaving a chemical reactor follows a decaying sinusoidal variation, according to the following mathematical equation,
t(t)=5e^(-at ).sin⁡(wt)
where a and w are constant.
then show that the temperature t (t) is maximum at time “t”. also verify that t= 1/w.〖tan〗^(-1) (w/a)
determine the maximum temperature value at t= 1/w.〖tan〗^(-1) (w/a).

You are traveling in a car going at a constant speed of 100km/h down a long, straight highway. you pass another car going in the same direction which is traveling at a constant speed of 80km/h. as measured from your car's reference frame this other car is traveling at −20km/h. what is the acceleration of your car as measured from the other car's reference frame? what is the acceleration of the other car as measured from your car's reference frame?

What do you think car designers do if the damage caused by a crash test is too severe?
