Sketch the region to see if your answer makes sense. 15. At time t = 0 a bolt falls from a helicopter which is hovering at an altitude of 4096 feet. Due to gravity, the bolt eperiences a constant acceleration towards the earth, a(t) = 32 ft./s 2. (a) Assuming the bolt was at rest when it began to fall, construct its velocity function, v(t). [Hint, the bolt had no initial velocity] Construct the bolt s displacement function s(t). [Hint, the bolt s initial displacement is the altitude of the helicopter] (c) After how long will the bolt hit the ground? 16. Evaluate the following integrals. Some will benefit from a substitution, others will not. (a) (c) sin(2) sin() d 3π/2 0 sin() d cos θ sin 5/2 θ dθ (d) (e) (f) 1 e z + 1 0 e z + z dz ( 2 + 1 + 1 ) d 2 + 1 e 1 ln d 17.
