This and the next two questions apply to this situation:A massive space freighter wants to accelerate at 4g. It takes time for the rocket engines to rev up,and turn up to their desired power. The freighter starts from rest, and its acceleration (until itreaches 4g) is:32ta(t) = - Ag2t3The captain wants to reach 4g at time t = T. What must A be, to satisfy a(T) = 4g? The desired final acceleration is now 3g, with a corresponding value for A. Recall:32t2t3Ta(t)-Ag%3DAcceleration feels like weight, and a rapid change in acceleration feels like a rapid change in weight.You don't want a too rapid change in weight -- the derivative a'(t) shouldn't be too great. Therefore:Take the derivative of a(t).Find t that maximizes a'(t).Answer T (in seconds) such that the maximum value of a'(t) is 1/60 m/s³.(If this were the actual test, I would give you t. Here, I urge you to figure it out.)

A 108 kg crate slides down a ramp, starting from rest. The ramp is inclined at an angle of 36.4 degrees with respect to the horizontal and has a height of 1.03 m. The crate is placed on frictionless casters so that it slides down the ramp without friction. What is the final speed of the crate (in m/s) just as it reaches the bottom of the ramp? Use g = 9.81 m/s².
